Latest Patents
One of Po-Cheng Chen's latest patents is related to a digital voltage regulator current sensing and regulation. This innovation involves using a reduced-size replica of power gate transistors within a closed-loop voltage regulator. The system measures the average current delivered by the transistors in the non-replica power gate. The measured current is compared against a known reference current, and a feedback loop modifies the gate bias of the power gate and replica power gate transistors. This improved current sensing solution allows for accurate current measurement through replicas, which closely matches the current in equivalent power gate devices.
Another notable patent is for a digital voltage regulator (DVR) with pulsed control and gradual non-linear control (NLC). This apparatus includes comparators that determine voltage load conditions and power gates that adjust output voltage based on a provided power gate code. The VR controller circuitry is designed to increase or decrease the power gate code in response to voltage load changes, ensuring optimal performance and stability.
