Latest Patents

Chang Ho An holds a patent for a "Rail-to-rail class-AB buffer amplifier with compact adaptive biasing." This invention features a rail-to-rail class-AB buffer amplifier that utilizes compact adaptive biasing. The design includes an input stage that generates a differential current pair based on the voltage difference between two input signals. Additionally, it has an amplification stage that outputs a driving signal based on this differential current pair. The output stage is connected to the amplification stage and produces an output signal. An auxiliary current source switch operates based on the driving signal, while a current mirroring unit generates and supplies bias current to the input stage when the switch is activated. This innovative approach enhances the efficiency and performance of buffer amplifiers.
