Connected to a differential transistor pair are a load current source and a tail current source. A bias circuit controls current generated by the load current source. A first self-bias switch is provided between a gate and a drain of a first input transistor; and a second self-bias switch is provided between a gate and a drain of a second input transistor, where the first input transistor and the second input transistor constitute the differential transistors pair. An external bias switch is provided between the bias circuit and the load current source.
