Latest Patents

One of Jianping Cheng's key patents is titled "Sigma-delta modulator with shared operational amplifier and associated method." This invention features a Sigma-Delta modulator that utilizes a shared operational amplifier (op-amp) within an integrated circuit. The design includes two integrators that share the op-amp, allowing for the integration of two input signals. Additionally, the modulator comprises multiple quantizers that compare the output signals of the integrators with a predetermined signal, generating digital output signals. The invention also incorporates several digital-to-analog converters (DACs) that convert these digital outputs back into analog feedback signals for the integrators. A clock generator provides the necessary clock signals to the integrating circuit and quantizers. This innovative design reduces both the layout area and power consumption of the modulator due to the shared op-amp.
