Latest Patents

Among his latest patents, Qiang Li has developed a "Low power dynamic inverter logic gate with inverter-like output." This invention features a dynamic circuit that includes a precharge circuit, a discharge circuit, and an output circuit. The precharge circuit charges a precharge node from the clock signal when the data input signal is low and the clock input is high. The discharge circuit discharges a discharge node to the clock signal when the data input signal is high and the clock input is low. The output circuit generates a logic high and a logic low as required by the data input signal. In another embodiment, the precharge circuit operates with a first clock while the discharge circuit operates with a second clock.

Another significant patent is the "Low power dynamic logic gate with full voltage swing operation." This invention utilizes recycled energy for dynamic low-power logic. It includes a discharge path, a precharge path, and a control circuit. The precharge path charges the output node to the logic high voltage of the clock line during a precharge phase. During the evaluation phase, the discharge path computes the desired logic function at the output node. The control circuit ensures that the precharge transistor fully charges the output node, providing recycled energy for circuit operation.
