Title: Gary G. Fang and His Digital-to-Analog Converter Innovations.
Introduction
Gary G. Fang is an inventor based in San Jose, California. His work includes innovations in digital-to-analog converters (DACs), particularly in switched R-2R ladder circuits and techniques for reducing glitches. He is associated with Maxim Integrated Products, Inc. His patent portfolio includes 5 patents.
Latest Patents
Fang’s listed patents address DAC performance and signal accuracy.
“Method and Apparatus for Digital to Analog Converters with Improved Switched R-2R Ladders” describes a circuit design that improves the operating range of R-2R ladders. The method increases resistance in series with a termination switch to help avoid transistor saturation as DAC resolution or reference-voltage range increases. The circuit is also modified to compensate for the added resistance and preserve resistor matching, supporting accurate analog output voltages for digital input signals.
“Method and Apparatus for Deglitching Digital to Analog Converters” presents asynchronous and synchronous controllers that manage sample-and-hold switches. The controllers detect changes in digital input codes and use one-shot pulses to place the sample-and-hold circuits in hold mode. The patent also describes secondary glitch cancellation circuitry that models the sample-and-hold environment, along with a differential amplifier designed to substantially cancel secondary glitches associated with parasitic charges.
Career Highlights
Fang’s disclosed inventions focus on practical challenges in DAC design, including maintaining performance across operating ranges and reducing unwanted output disturbances. His work at Maxim Integrated Products, Inc. connects these innovations with the development of electronic components and signal-conversion technologies.
