发明名称 Amplifier including dithering switch and display driving circuit using the amplifier
摘要 An amplifier and a display driving circuit. The amplifier includes an input stage, a bias stage and an output stage. The input stage determines voltage levels of two nodes in correspondence to two input voltages received in response to a first bias voltage, and includes four path selecting switches, two input transistors and one bias transistor. The bias stage generates two class AB output voltages which correspond to the voltage levels of the two nodes, and includes current mirrors, ten path selecting switches, class AB bias circuits and two bias transistors. The output stage generates an output voltage VOUT that corresponds to the two class AB output voltages, and includes two coupling capacitors and two push-pull transistors. The plurality of path selecting switches operate by one signal of a first path selecting signal and a second path selecting signal that are exclusively enabled with respect to each other.
