C. V. For Henning Petersen


Personal:

Bachelor of Engineering, graduated from Københavns Teknikum in 1993. Started playing with electronics at the age of 12, computer programming at the age of 14. Now Senior Asic Designer, RF/analog/mixed. RF system budgets – system architect.


Work style: Thorough, systematic, determined, good planner and administrator. Skilled in writing clear, thorough documentation. Easy learner. Keeps track of top overview and the details.


Besides design, some of my forces are planning, documentation, clear communication and administration. These are key parameters in achieving success with the system integration, e.g. assuring that the blocks together will make the entire chip work as thought. This is especially important in cross site projects, and of course in the work with external customers and vendors.


I have a broad knowledge of the many aspects of engineering, administrative methods and business areas, gained through 17 years of experience: as employee at the university, in large international companies, and in a small startup company, financed by investors and project sales; within both chip design and discrete electronics design.


I have lived abroad for a period, and throughout my career I have worked with customers/vendors/sites in Denmark, Japan, Korea, Sweden, Finland, Norway, France, Germany, US, UK and Israel. My current residence is Copenhagen, Denmark.


As a person, I am regarded as a friendly colleague, always ready to help with job tasks or elsewhere.

Elaborating on the CV


Analog design:

Developed and worked with a very broad range of analog/mixed signal circuits, many of them with tough specs. To mention a few: high gain ultra low power wakeup detector, opamps (normal or input/output rail-to-rail), high performance low noise highly linear opamps, bias and bandgaps, active high order filters, regulation systems, chip design for Hifi audio. Worked with Mentor Graphics programs like Design Architect, Eldo, IC Station, and the related DRC and LVS programs. APLAC super user. PSpice advanced level.


Low noise design:

Developed low noise designs in both LF (pre amplifiers, sensitive bias circuits) and RF (LNA, RX mixers) frequency ranges. Theoretical insight in the theory behind noise, thermical as well as 1/f noise. Familiar with noise calculations on device and circuit level, and also through spreadsheet noise budgetting. Knowledge of noise coupling from noisy blocks (through substrate/package) and the techniques to reduce the coupling and the impact.


Low power design:

Developed several circuits in μA-range, down to 1.2 Volts. Circuits were used in hearing aids and RTTT circuits (traffic control units, like for example BroBizz). I know how to combine low noise and low power designs by having clear overview of the system budget, meaning that the necessary power will be used in the block(s) where the benefit is maximized.


Low cost design:

Worked in the mobile phone business, and on an RTTT project. In both the mobile and the RTTT business, cost is very important. As such, I have been involved in the tradeoffs of chip area and package choice, as well as the cost of production test time, for example by cutting down the test time to include only the necessary tests, while ensuring only working devices to pass the tests.


RF design:

Developed and worked with a very broad range of RF circuits, among these LNA's, RX/TX mixers, direct conversion and heterodyne receivers/transmitters, PLL's and VCO's, PA's, AGC/VGA's, RSSI. Also worked with system design; I have planned an entire ZigBee receiver where I had full liberty to select the receiver chain architecture, demodulation principle, and the interface to, and the system design of the digital baseband.


Switched amplifiers/power stages:

Designed class D nmos/pmos 0,35μm 250 mW output driver stages (100MHz-2GHz), and their prestage drivers, these were verified/tested on silicon. Designed discrete class F power amplifiers at frequencies 100/200/945 MHz, with semiconductors of the types LDMOS and GaN. Verified to work. These designs were thoroughly simulated, while acquiring theoretical and practical knowledge. Worked extensively with class F amplifier technology. Designed microstrip boards especially for switched amplifiers. Presently working with high end class D audio amplifiers.


Circuit design in general:

Please see the extensive list of blocks included in the general CV above. These designs have involved noise analysis, stability analysis, analysis over temperature, supply voltage, and statistical analysis (Monte Carlo) to determine and improve robustness. Analysis has been performed as DC, AC, steady state and transient analysis, as well as mixed system/analog analysis.


Mass production:

All chip designs have been targetted for mass production. In Nokia, the design teams did the chip design from specification to handling production. I participated in this process all along, and is used to the concept of designing for test, specifying test plans and making robust designs through Monte Carlo simulations and other techniques. My first chip project in Nokia shipped millions of chips, another shipped 350 millions, and I understand the importance of designing fault free circuits when designing for multi million production, and know the techniques used.


Process and modelling experience:

AMS, Infineon, Magna Chip, FD-SOI (from a large Japanese foundry, developing a fully depleted silicon on insulator process) as well as other processes not to be disclosed. Extensive insight and experience with various models (BJT/CMOS/HBT/SOI-CMOS/LDMOS), including verification and correcting errors/improving models. Insight in chip fabrication, mask stages, packaging, ESD-protection and requirements.


Chip layout:

At both Nokia and Silicide, I did the layout personally including pad ring, interconnecting, and block layouts. Also running DRC and LVS. Knowledge of the parasithic phenomenons that limit the designs, knowledge of how to modify the simulation profiles to reflect parasithic limitations, found by parasithic extraction and by estimating unknown parasithics. Knowledge of coupling through substrate and what to do. Experience within the area of package modelling/parasithics. Done layout in IC Station and Catena Layed.


Simulation and design experience:

My major force is working with simulators, analog/mixed signal and discrete time system simulators, like Aplac (nowadays part of the AWR simulator suite, HP-ADS, Eldo (Spice), PSpice. I have designed reference code for the WLAN (802.11a/b/g) and Hiperlan 2 system simulators in a commercially available simulator.


Testing and lab experience:

Extensive lab experience in the range DC - 4 GHz, oscilloscope, fft, network, spectrum analyzer, DC current/voltage measuring. Experience with automated measurement setups and processing the data. Knows how to use a soldering iron, experienced in RF matching; I know my Smith charts.


PCB and microstrip design:

Supervised many PCB designs, low/high power, low/high frequency. I have designed microstrip boards, Duroid/FR4.


Project management, project specification:

I have conducted and managed many feasibility studies, working with French, Danish and Japanese customers. I had responsibility for a 5 person group of IC designers in Nokia.


IT/computers:

Worked with scripting, automated/batch simulating, data processing from statistical/batch simulation setups. Knowledge to a broad range of EDA software like ELDO, HP-ADS, APLAC, Mentor Graphics suite, Layed, PSpice Linux power user. Have worked with remote access and management like backup, setup of home office running through command line and graphical interface (X11)
