Latest Patents

Rohini Abhyankar holds a patent for "Phase-locked loop systems using adaptive low-pass filters in switched bandwidth feedback loops." This patent describes 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 her invention provides 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 provides an output signal, along with a divider that receives the output signal and divides it to provide the reference signal. This innovative approach enhances the performance and efficiency of PLL systems.
