Biography

J.F. (Frerik) Witte was born in Amsterdam, the Netherlands, on March 16, 1979, where he lived until finishing his high school education (Atheneum) at the Pieter Nieuwland College in 1997. In that year he moved to Delft to start his studies in electrical engineering. He received his M.Sc. degree in electrical engineering (cum laude) from Delft University of Technology in 2003. The subject of his M.Sc. thesis was “On-Chip Time References and Electro-Thermal Oscillators”. In 2003, he started working towards a Ph.D. degree at the Electronic Instrumentation Laboratory of Delft University of Technology. The subject of his research was to design low-offset broadband CMOS amplifiers, which resulted in this book. From January to April 2003, he did an internship at Philips Semiconductors, San Jose, California, where he worked on integrated diagnostic circuits to measure the value of an external capacitor. Since January 2009, he is working as a senior design engineer for National Semiconductor at Delft. His professional interests include sensors, precision analog and mixed-signal design. He received the ESSCIRC 2006 Young
Scientist Award.

  1. A ping-pong-pang current-feedback instrumentation amplifier with 0.04\% gain error

    Abstract: ... A ping-pong-pang auto-zeroed and chopped current-feedback instrumentation amplifier (CFIA) uses three dynamically-matched input stages to achieve 0.04\% gain error, a 2.5× improvement over prior art. Its 4 μV offset and 28 nV/√Hz noise are achieved at 3.5× less supply current than a comparable ping-pong auto-zeroed CFIA.
