Title: Gaurav Chandra: Innovator in Circuit Design and Monitoring Technologies

Introduction

Gaurav Chandra is a notable inventor based in Richardson, TX (US), recognized for his contributions to circuit design and monitoring technologies. He holds a total of 10 patents, showcasing his innovative approach to solving complex engineering challenges.

Latest Patents

One of his latest patents is a "Process and temperature insensitive flicker noise monitor circuit." This invention involves an apparatus and method for monitoring defects in wafers. A monitoring circuit is fabricated on an area of each wafer, including representative devices that replicate similar devices located in a die area. If defects are present in the representative devices, they contribute to noise generation, causing an imbalance in a measurable differential signal. A digitizing circuit uses a common mode voltage as a reference to measure this imbalance, digitizing the differential signal into a digital signal indicative of the noise generated by the defects. This digital signal is stored over a configurable time interval to form a digital bit stream, which is then compared to a reference to determine if the defects are within an allowable range.

Another significant patent is for "Methods and apparatus for error cancelation in calibrated current sources." This invention describes a digital to analog converter that converts digital bits into an analog output signal. It includes a plurality of current sources, a calibrator, and a current source selector. The current sources output substantially identical currents, and the calibrator is selectively coupled to calibrate the current sources to a reference current. The current source selector assigns respective current sources to the digital bits based on a bit-to-current source sequence selected to reduce current error in the analog output.
