发明名称 Differential output circuit with stable duty
摘要 A differential output circuit includes a bias circuit connected with a first voltage. An input circuit section includes first and second MOS transistors of a first conductive type, and the first and second MOS transistors are connected with the first voltage through the bias circuit, and gates of the first and second MOS transistors receive a differential input signal. Third and fourth MOS transistors of a second conductive type are connected with the first and second MOS transistors through first and second resistance elements, respectively, and connected with a second voltage. A first connection node between the first MOS transistor and the first resistance element is connected with a gate of the fourth MOS transistor, and a second connection node between the second MOS transistor and the second resistance element is connected with a gate of the third MOS transistor. A differential output signal is outputted from a first output node between the first resistance element and the third MOS transistor and a second output node between the second resistance element and the fourth MOS transistor in response to the differential input signal.
