I specialize in Analog Mixed-signal (“AMS”) architecture, debugging, modeling, and verification. Have worked on 40+ analog/digital mixed-signal CMOS ICs, directly responsible for the design and mass production of over a billion units. Experienced in complete product lifecycle, from initial conception through design, verification, fabrication & testing. I have worked with many major clients in Silicon Valley and beyond to provide them with R&D engineering services and tools for AMS architecture, design, and verification of silicon integrated circuits. I have deep knowledge in all aspects of digital ASIC, analog CMOS, mixed-signal and RFIC intellectual property and can assist your attorney in patent related projects including prior-art searches, patent claims analysis, review of patent applications, and litigation support as a subject matter expert. My IP consulting experience include: • Analysis of utility patents for infringement, and reviewed technical documents to elucidate and e...

David Chapman is an experienced software developer who has written over 1,300,000 lines of code in C/C++ and other languages. He has written software for many areas of semiconductor electronic design automation: mask data preparation, design rule checking, circuit extraction, circuit delay characterization, logic synthesis, physical synthesis, placement, routing, Intellectual Property identification, and transistor level layout generation. He has over 20 years of consulting experience and was the chair of the Consultants' Network of Silicon Valley in 2018-2019. He has 12 U.S. patents granted. His expert witness work to date has focused on discovery/analysis of semiconductor layouts (GDS/GDSII, OASIS), especially for patent infringement. His sharp eyes plus his understanding of semiconductor processing and design tools mean that if it's there, he can find it.

My sub-specialty within the broad category of electrical engineering is with integrated circuits (or complete systems) used for signal-processing, which • Detect signals from a sensor (e.g. antenna, microphone etc. • Amplify, filter, then convert to digital • Process further in the digital domain • Convert the result back to the analog domain for further processing, and/or • Deliver the final output to an actuator (e.g. antenna, speaker, video display, heater control-switch etc.). Examples of these systems are • Mobile and cell phones • Recording and retrieving systems for disk drives or tape • Radio transmitters/receivers and their building blocks such as low noise amplifiers, filters, automatic gain control and frequency mixers (down-converters, up-converters) • Audio amplifiers • Audio recording/reproduction systems • Heat, ventilation and air conditioning controllers • Data transmitting/receiving systems such as serializer/de-serializers (SERDES)
