With a total of 2 patents to his name, Ding's work has had a substantial impact on programmable logic devices.
Latest Patents
Ding's latest patents focus on power-on-reset circuitry designed for integrated circuits, such as those used in programmable logic devices. This innovative circuitry employs comparator-based trip point voltage detectors to monitor power supply voltages. The trip point detectors generate trip point voltages from a bandgap reference voltage. Additionally, controller logic processes signals from these detectors to produce a corresponding power-on-reset signal. The circuitry includes a noise filter to suppress noise from power supply voltage spikes, ensuring reliable operation. During testing, normal operation of the power-on-reset circuitry can be blocked, and it may be disabled if the bandgap reference voltage has not reached the desired level. The design can be sensitive or insensitive to the power-up sequence used by the power supply signals. Furthermore, brownout detection blocking circuitry is incorporated to prevent the output from one of the trip point detectors from influencing the power-on-reset circuitry.
