Latest Patents

Wenrong Qian's latest patents include a Voltage Regulator and a Regulated Charge Pump Circuit. The Voltage Regulator patent describes a regulator circuit that includes an output circuit, an error detection circuit, and an intermediate circuit. The output circuit is designed to receive a first supply voltage and regulate a second supply voltage based on a control signal. The error detection circuit compares the second supply voltage with a reference voltage and generates an error signal indicative of the difference. The intermediate circuit generates electrical currents based on the error signal and the second supply voltage, ultimately producing the control signal.

The Regulated Charge Pump Circuit patent outlines a circuit for providing a power supply. This circuit features a control signal generator and a switch network circuit. The control signal generator creates a control signal based on the output voltage on a load capacitor. The switch network circuit, which is coupled with the load capacitor and a flying capacitor, forms a charge pump circuit. It charges the flying capacitor in a charge stage and pumps it in a pump stage to generate a stable output voltage on the load capacitor.
