Bio
Ivan Mollov
Gerhard is highly experienced analog and mix-signal ASIC designer with A to Z first hand knowledge of the design process. This includes concept design, simulation with foundry models, layout design, DRC based on foundry information and communication with both, foundries and external design outfits. His innovative approach to every design is documented by the many patents he has received over the years. He is detail oriented and has designed ICs which are in manufacturing at rev A. I highly recommend him as a designer in the area of analog and mix-signal IC design.
David Wilding
Gerhard is an innovative ASICs design engineer. It was a pleasure to work with him on a number of his patent applications. He has a wealth of knowledge about circuit design and is personable and helpful. He helped to build Varian and Varex's patent portfolio in X-ray detection technology. His experience and creativity will be missed.
