Title: Gangqiang Zhang: Innovator in Differential Amplifiers and Over-Voltage Comparators
Introduction
Gangqiang Zhang is a notable inventor based in San Jose, California. He has made significant contributions to the field of electronics, particularly in the development of differential amplifiers and precise over-voltage comparators. With a total of two patents to his name, Zhang's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
Zhang's latest patents include a differential amplifier having an improved slew rate. This differential amplifier is designed to receive a differential input signal and generate an output signal at an output node. An auxiliary circuit coupled to the differential amplifier enhances the slew rate response. In quiescent and small signal situations, the auxiliary circuit does not alter the operation of the differential amplifier. However, during large signal changes, the auxiliary circuit accelerates the sourcing and sinking current to and from the output node. This results in a quicker charging or discharging of a stability compensation capacitor, thereby improving the slew rate performance of the differential amplifier.
Another significant patent is the zero-waiting-current precise over-voltage comparator. This comparator exhibits zero-waiting-current characteristics during normal working conditions. It utilizes an NMOS transistor along with other circuit elements to regulate its operation. Under normal power supply voltages, the comparator remains in standby mode, consuming no quiescent current.
