Title: Innovations of Sri Ram Gupta
Introduction
Sri Ram Gupta is a notable inventor based in Bengaluru, India. He has made significant contributions to the field of electronics, particularly in the development of advanced analog-to-digital converters and ambient light sensors. With a total of four patents to his name, Gupta's work showcases his expertise and innovative spirit.
Latest Patents
One of Gupta's latest patents is the "Multichannel Successive Approximation Analog-to-Digital Converter." This invention includes a digital-to-analog converter (DAC) that is designed to receive a digital signal. The first conversion units of the DAC are configured to sample an analog signal via a first switch and provide a first level voltage. Each first conversion unit comprises a first capacitor array and a first switch array controlled by the digital signal. Additionally, a single second conversion unit of the DAC is designed to provide a second level voltage, which includes a second capacitor array and a second switch array. A comparator is utilized to compare each of the first level voltages to the second level voltage, generating a comparison signal based on each comparison and the actuation of a set of third switches. A control circuit is responsible for closing the first switches simultaneously and the third switches successively for the conversion of each sampled analog signal.
Another significant patent is the "Ambient Light Sensor and Method." This invention features a photodiode that generates an electrical signal based on ambient light. It includes a capacitive-feedback transimpedance amplifier connected to the photodiode, which amplifies the signal generated. The ambient light sensor also incorporates an auto-zero switch at the input of the amplifier. Furthermore, a control circuit with a bootstrap circuit is designed to receive an initial positive or zero-voltage logic control signal, generating an adapted logic control signal with distinct voltage levels for controlling the auto-zero switch.
