Title: Anubhuti Chopra: Innovator in Analog Front-End Systems

Introduction

Anubhuti Chopra is a notable inventor based in Delhi, India. She has made significant contributions to the field of analog front-end systems, holding 2 patents that showcase her innovative spirit and technical expertise. Her work primarily focuses on enhancing the performance of variable-gain amplifiers and digital-to-analog converters.

Latest Patents

One of Anubhuti's latest patents is titled "Offset calibration for an analog front-end system variable-gain amplifier." This invention provides a method for offset calibration that mitigates errors in variable-gain amplifiers. The calibration process employs a difference-based estimation technique combined with digital iteration, which effectively measures different digital output signals from an analog-to-digital converter. This innovative approach ensures that the digital output difference converges to a target of zero volts.

Another significant patent is the "Segmented digital-to-analog converter." This invention involves a digital-to-analog converter (DAC) that transforms an input digital signal into an output analog signal. The DAC consists of two segments, a combiner, and a controller. The first segment generates a first analog signal in response to a portion of the digital signal, while the second segment generates a second analog signal for another portion. The combiner then merges these signals to produce the final output. This segmented DAC design is particularly suitable for use in sigma-delta analog-to-digital converters.
