Title: Onkar S Modgil: Innovator in Power Control and Analog-Digital Conversion

Introduction

Onkar S Modgil is a notable inventor based in Mesquite, TX (US). He holds 2 patents that showcase his expertise in power control systems and analog-to-digital conversion technologies. His innovative contributions have made significant impacts in the fields of electronics and signal processing.

Latest Patents

One of Modgil's latest patents is a Closed Loop Power Controller. This power controller features a closed-loop system that utilizes a summer to combine an input signal with a derived output signal, resulting in a difference signal. A comparator then assesses this difference signal against a reference signal, generating a digital signal that indicates the polarity difference. The system employs two switching networks that respond to the digital signal, producing high-energy outputs to reduce the difference signal level within a specific frequency band. Additionally, a low-pass filter is integrated to attenuate high-frequency noise, enhancing the signal-to-noise ratio, particularly in audio frequency applications.

Another significant patent by Modgil is related to Methods and Apparatus for Analog-to-Digital Conversion. This invention includes a high-frequency pulse source, which is a variable frequency oscillator whose output frequency is dependent on an analog condition. The system also incorporates a reference signal source with a fixed frequency, which is a fraction of the oscillator's frequency. A counter-divider adjusts the output based on the phase difference between the reference signal and the counter-divider's output pulses. This innovative approach allows for precise control and measurement of phase differences, ultimately producing a binary word through a digital low-pass filter.
