Latest Patents
Wangke Tao holds a patent for an "Error amplifier with accurate output clamp function." This invention presents a high-performance error amplifier concept and unique circuitry architecture designed specifically for controllers of SMPS. The error amplifier features a front-end buffer circuit, an embedded differential amplifier, an N-MOSFET based output driving stage, and a coupled passive RC network. The embedded error amplifier is constructed with two differential pair inputs and an output amplification stage. The N-MOSFET output stage, coupled to the output of the embedded differential amplifier, enhances the load driving capability of the proposed error amplifier. The clamp voltage can be configured by another passive network and an output stage with two current sources. This invention allows users to arbitrarily configure the clamp voltage level regardless of the error amplifier's bias voltage. Additionally, the highly accurate clamp voltage level can be achieved without temperature drift issues.
