Expert is a Licensed Professional Electrical, Electronics Engineer, and Expert Witness practicing forensic and technical electrical engineering consulting. His forensic engineering practice includes forensic investigation, advising, reporting and testimony in electrical, electronic, communication, and electro-mechanical control-system matters regarding intellectual property, patents, failure analysis, product liability, injuries, product requirements and specifications. His technical engineering practice includes the design, verification, measurement and testing of electronic signal processing hardware circuits and systems, both integrated circuits and electrical modules, which are used for communication and electro-mechanical control.

Examples of communication and control systems are:
• Internet of Things (IOT) systems

• Remote control systems for hobbyist aircraft and vehicles
• Pressure sensors for reading depth of fluid column
• Electrical equipment power and grounding

As a technical consultant, Expert has broad and deep understanding of analog/mixed-signal (AMS) circuits and systems, as well as strong experience with design verification, especially for chip-level analog and mixed-signal ICs. He independently reviews and verifies digital and analog/mixed-signal ICs using electronic design automation (EDA) software before funds are committed to manufacturing the design.

• Advise and provide solutions for top-down design methodologies, and the analysis, design, modeling and verification of RF, analog and digital circuits. For design verification (DV) of Systems-on-Chip (SOC) with embedded AMS sub-systems I develop DV strategies, verification plans, create behavioral models and test-cases to execute the verification-plan (V-Plan)
• Create behavioral models of electrical circuits, wireless system components and electro- mechanical units to be used for DV. DV languages include universal verification methodology (UVM), System Verilog (SV) using real-number modeling (RNM) of analog signals and systems, Verilog, Verilog- AMS, VHDL, VHDL-AMS, Verilog-A, Spice, Spectre and others
• IC Circuit-Design and DV tools include those by Cadence and Mentor Graphics
• Design algorithms, software, and hardware for system self-tuning and calibration

Client products include:
• Lithium Ion Battery Management Systems
• Single-chip Transceivers for Products with Antenna Diversity
• Hard-Disk-Drive READ-Channel integrated circuits
• Single-Chip RF Television Receivers
• High Speed Serializer/De-serializer (SERDES) Circuits
• Mixed-signal Power management ICs comprising low drop-out (LDO) and switch-mode step-up (boost) and step-down (buck) converters intended for medical or general applications
• Magnetometers (for sensing magnetic field intensity and angle)
• Analog/Mixed-Signal Computer-Aided Design (CAD) Tools

Notable projects for clients:
• Examined Lithium Ion Battery schematics and algorithms, and advised on design process and methodology
• Taught in-house class “An Introduction to Mixed-Signal Behavioral Modeling and Verification” for engineering and engineering management staff of client company
• Designed electronic system components for a high-accuracy magnetic field sensor
• Created and validated Matlab/Simulink models for top-down design and verification of that complete magnetometer system
• Designed an optimal self-tuning algorithm for a local-oscillator generator’s phase-locked-loop
• Designed a self-calibration mechanism for poly-phase filters used in a Television Receiver RF front end

Expert may consult nationally and internationally, and is also local to the following cities: New York, New York - Yonkers, New York - Newark, New Jersey - Jersey City, New Jersey - Paterson, New Jersey - Elizabeth, New Jersey - Trenton, New Jersey - Philadelphia, Pennsylvania - Allentown, Pennsylvania - Stamford, Connecticut
