Latest Patents
Liu's latest patents include a gate driving circuit that comprises a driver control circuit, a voltage following bias circuit, a pull-up circuit, and a MOS transistor. This innovative circuit allows for the generation of pull-up or pull-down signals based on an active signal. When the pull-up signal is activated, the MOS transistor is turned off, preventing current flow to the output load device. Conversely, when the pull-down signal is activated, the MOS transistor is turned on, providing a constant current for the output load device.
Another notable patent focuses on methods and circuits designed to reduce power consumption in DRAM local word-line drivers. This invention utilizes a first voltage converter to provide a voltage VPP that is lower than what is typically required for operating a word-line in a DRAM cell array. A voltage detector monitors the voltage level, ensuring that the final VPP voltage is applied efficiently, thereby reducing overall power consumption.
