Jacob Elias Fæster Overgaard
My name is Jacob Elias Fæster Overgaard, I have a Master of Science in Electrical Engineering degree from the Technical University of Denmark. I started my career at ICEpower in 2015 working on class-D audio amplifiers and quickly found love for the domain of power electronics. Throughout my studies I continuously honed my skills within power electronics and integrated analog circuits.
When I commenced my Honorary Programme on my Master’s of Science in Electrical Engineering I switched to working as a technical assistant for the Technical University of Denmark, my location of studies.
After finalizing my studies I began my career as an Analog IC Engineer with the Danish hearing aid manufacturer, GN Hearing. Here I worked on analog and mixed-signal designs an RF ASIC intended for magnetc induction near-field communication. Following an approximately two-year stint I switched to work in integrated power-management ICs and modules with Lotus Microsystems, a Danish fabless semiconductor startup, spun out from the very group at the Technical University of Denmark I was affiliated with.

GN Hearing, Denmark, Ballerup
Analog IC Engineer (2020 – 2022)
As an Analog IC Engineer at GN Hearing I worked primarily on an RF ASIC used for magnetic induction near-field link between hearing aids. My work spanned from individual contribution to close teamwork with the remaining analog and digital design engineers as well as close collaboration with external and internal stakeholders.
- Worked with medical MDR-regulated devices with high demands for regulatory compliance.
- Mixed-signal verification of RF ASIC for magnetic induction communication and mixed-signal tool-flow setup for DSP ASIC. For the mixed-signal flow I used Spectre and Incisive as well as TCL for testbench stimulation and verification.
- Floorplan and ESD-planning of RF ASIC in collaboration with technical project lead.
- Design of various general purpose analog circuits including comparators, operational amplifiers
- Specified components, specifications and capabilities for internal test board of RF NFMI IC with a focus on automated testing
- Automated python test flow for verifying block-level and chip-level specifications according to a detailed verification plan.
- Created an automated mixed-signal simulation suite for running Cadence simulations extracting verification results and reporting.
CERN, Switzerland, Geneva
Intern, back-end electronics (Summer 2019)
Tasks including developing a fully automated test bench in Python for evaluating commercial power supplies. The verification campaign was used to evaluate possible vendors in a public bid for supplying the back-end power supplies for the 2024 CERN LHC upgrade.
Technical University of Denmark, Denmark, Kongens Lyngby
Technical Assistant (2018 – 2020)
I was responsible for internal development of electrical circuitry, intended for internal use as well as development of prototypes/demonstrators for research projects.
- Design of a synchronous rectifier using both PLL and DLLs using DTU-designed integrated circuits.
- Design of a 1 W 230V offline flyback power converter with primary-side regulation.
ICEPower, Denmark, Søborg
Student Assistant (2015 – 2018)
As a student assistant in the R&D group of ICEpower A/S, had the task of developing and realizing various test jigs for EMC, safety and regular product testing. Furthermore I modified an ICEpower audio amplifier to create a capacitive driver with a 1/f closed-loop gain for constant output power vs. frequency. This included manual rework of the audio amplifier as well as design modifications, debugging and testing.
Another task included creating a power-stage for circumventing bus bumping caused by power-rail run-back currents. I designed the amplifier and created the corresponding power-stage and verified the functionality of its capabilities in reducing bus pumping.
I also carried out tests of ICEpower’s products, including audio performance verification via the Audio Precision audio analyzers as well as power supply verification.
