With a total of 2 patents to his name, Hu has demonstrated his expertise and innovative spirit in developing advanced electronic components.
Latest Patents
Among his latest patents is a CMOS output driver that can tolerate an output voltage greater than the supply voltage. This mixed mode buffer circuit includes a first input, a second input, and an output, allowing for a voltage exceeding the supply voltage to be applied without causing latchup or increasing leakage current. The design features an output transistor of a first conductivity type, which is coupled to the output and controlled by the first input. Additionally, a lock recovery circuit for a phase locked loop has been developed by Hu. This circuit provides recovery when the phase locked loop has lost lock on an input reference signal, utilizing an override circuit to manage the voltage at the input of a voltage-controlled oscillator (VCO).
