Title: Haiming Tang: Innovator in Phase-Locked Loop Technology
Introduction
Haiming Tang is a notable inventor based in Cupertino, CA. He holds a total of 5 patents that showcase his contributions to the field of electronics and signal processing. His work primarily focuses on advanced technologies that enhance the performance of electronic devices.
Latest Patents
One of Haiming Tang's latest patents is a "Wideband phase-locked loop for delay and jitter tracking." This innovative device includes feed-forward clock circuitry that provides a receiver clock to a sampler circuit, which samples a data lane of a set of receiver data lanes. The feed-forward clock circuitry is designed to account for temperature-induced delays. Additionally, the device features an RX phase-locked loop (PLL) that is coupled between the feed-forward clock circuitry and the sampler circuit. The RX PLL incorporates a phase interpolator positioned in its feedback path, which has a negative delay that matches the temperature-induced delay of the feed-forward clock circuitry. This design allows the sampler circuit to effectively cancel out common noise shared between the feed-forward clock circuitry and the data lane.
Another significant patent is the "Voltage-to-current converter." This conversion circuit includes a super source follower circuit that lowers the impedance of a first node. A digital control circuit adjusts the current at the first node based on the current through the super source follower. The output transistor in this circuit has a gate configured to receive a first signal, with its drain coupled to the first node. The source of the output transistor is designed to output an output current based on the voltage of the first signal.
