Semiconductor Expert Witnesses

Semiconductor expert witnesses and consultants listed here may be able to form expert opinions, draft expert witness reports, provide expert witness testimony at deposition and/or trial as or serve as consulting (non-testifying) experts on semiconductor. The semiconductor expert witness listings on this page are typically from fields/areas of expertise such as: Electronics, Engineering, and Intellectual Property.

David Chapman

San Jose, California
Intellectual Property, Electronics - Software, Electronic Design Automation, EDA, Semiconductor, GDS, GDSII, OASIS
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.

Robert O Peruzzi, PhD, PE R. Peruzzi Consulting, Inc.

Bethlehem, Pennsylvania
Electronics, Engineering - Integrated Circuits (ICs), Patent Infringement, Mixed-Signal, Analog, Radio Frequency (RF), Signal-Processing, Analog-to-Digital (A/D), Digital-to-Analog (D/A), Control Systems, Semiconductor, System on Chip, SOC
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)
