Title: Ragu Sridhar: Innovator in Phase-Locked Loop Systems
Introduction
Ragu Sridhar is a notable inventor based in San Jose, California. He has made significant contributions to the field of electronics, particularly in the development of phase-locked loop (PLL) systems. His innovative work has led to the creation of a patent that enhances the functionality of PLL circuits.
Latest Patents
Ragu Sridhar holds a patent for "Phase-locked loop systems using adaptive low-pass filters in switched bandwidth feedback loops." This invention focuses on methods and systems directed toward a PLL circuit that includes a local lock detector receiving an error signal and providing a lock signal. Additionally, a charge pump receives the error signal and provides a charge signal. The loop filter in this system is designed to provide both a first and a second loop filter bandwidth. It includes a first low-pass filter that alters its characteristics in response to the lock signal, providing a first filter signal. Furthermore, a second low-pass filter is configured to receive the first filter and lock signals, also altering its characteristics based on the lock signal to provide a loop filter signal. The PLL circuit incorporates a voltage-controlled oscillator (VCO) that receives the loop filter signal and generates an output signal, along with a divider that divides the output signal to provide a reference signal.
