Latest Patents

Zhongkai Wang holds a patent for a clock and data recovery (CDR) circuit that employs a zero-crossing linearizing (ZCL) technique. This circuit includes a voltage-controlled oscillator (VCO), an inject-locked divider (ILD), a variable delay unit, a linearized loop, a bang-bang loop, and a loop filter (LP). The differential clock generated by the VCO passes through the ILD for frequency division and the variable delay unit to produce 8-phase clocks. These clocks enable the phase detectors (PDs) to over-sample the input data, followed by synchronization and logic operations to control the charge pumps (CPs) output current pulses. The currents filtered by the LP regulate the VCO to complete the loop. This circuit effectively recovers 4-channel data and corresponding clocks from the input while maintaining low power consumption and excellent jitter performance and locking properties.
