Ken co-founded Designer’s Guide Consulting in 2005 where he helps design companies adopt analog verification by providing a unique model generation and validation tool. Prior to that he worked at Cadence Design Systems as a Fellow. Ken created Spectre and was the principal architect of the Spectre circuit simulation family. As such, he has led the development of Spectre, SpectreHDL, and SpectreRF. He also played a key role in the development of Cadence’s AMS Designer and made substantial contributions to both the Verilog-AMS and VHDL-AMS languages. He has written three books on circuit simulation: The Designer’s Guide to Verilog-AMS in 2004, The Designer’s Guide to SPICE and Spectre in 1995, and Steady-State Methods for Simulating Analog and Microwave Circuits in 1990; and created The Designer’s Guide Community website. Ken received his Ph.D. in Electrical Engineering from the University of California at Berkeley in 1989 and became an IEEE Fellow in 2007 for contributions to simulation and modeling of analog, RF, and mixed-signal circuits.
