Latest Patents
One of his latest patents is a PAM-4 receiver with jitter compensation clock and data recovery. This innovative receiver includes a first-order delay-locked loop (DLL) that employs a bang-bang phase detector (BBPD) and a voltage-controlled delay line (VCDL) circuit. It supports a 40 MHz jitter tracking bandwidth and static phase skew elimination. Additionally, a second-order wideband phase-locked loop (WBPLL) utilizes a β-rate reference clock to provide multi-phase clock generation with low input-to-output latency. To suppress jitter transfer, a jitter compensation circuit (JCC) detects the DLL loop filter voltage (VLF(s)) signal and generates an inverted loop filter voltage signal. This configuration allows for a jitter compensation ratio of up to 60% from DC to 4 MHz, with a -3-dB corner frequency of 40 MHz.
Another significant patent involves adaptive cascaded equalization circuits with configurable roll-up frequency response for spectrum compensation. These circuits are designed to compensate for signal loss in wire-line or optical communications. The cascaded equalization circuits consist of two or more stages of equalizers, each with different peaking frequencies. This unique configuration allows for an overall frequency response with a roll-up slope, and the equalization function is automatically tuned by an adaptive feedback control loop.
