Title: Hiva Hedayati: Innovator in Clock Distortion Correction
Introduction
Hiva Hedayati is a prominent inventor based in San Jose, CA. He has made significant contributions to the field of clock distortion correction, holding a total of 6 patents. His work focuses on enhancing the accuracy and efficiency of clock signals in high-speed applications.
Latest Patents
Hedayati's latest patents include innovative techniques for offset insensitive quadrature clock error correction and duty cycle calibration for high-speed clocking. These techniques involve circuitry designed to detect and correct duty cycle distortion and quadrature clock phase distortion. The phase detection circuitry is simplified and made more accurate through a sampling operation that accounts for device mismatch within the detection circuitry. By sampling charge associated with an ideal clock signal across sampling capacitors, the stored charge compensates for device mismatch, thereby improving detection accuracy. Additionally, a common mode voltage is applied to sampling capacitors to zero the voltage differential, compensating for any offsets that may arise from other components in the detection circuit. A feedback algorithm utilizes a digital value to correct clock distortion effectively.
Another notable patent involves asynchronous clock generation for time-interleaved successive approximation analog to digital converters. This clock generator receives a global clock signal, a completion signal, and differential outputs from a comparator during a conversion cycle. A logic circuit generates a control clock signal based on these inputs and can disable the control clock signal in response to the completion signal, indicating the end of required conversion cycles.
