Latest Patents
Jianqiu Chen holds a patent for a "Sigma-delta modulator with shared operational amplifier and associated method." This innovative design features an integrated circuit that includes two integrators sharing a single operational amplifier (op-amp). The modulator is capable of integrating two input signals, which enhances its functionality. The design also incorporates multiple quantizers that compare the output signals of the integrators with a predetermined signal, generating digital output signals. Additionally, it includes several digital-to-analog converters (DACs) that convert these digital outputs back into analog feedback signals. A clock generator provides the necessary clock signals to the integrating circuit and quantizers. This design effectively reduces layout area and power consumption due to the shared op-amp, showcasing Jianqiu Chen's commitment to innovation in electronic design.
