Abstract
An amplifier circuit for amplifying an input signal and obtaining true and complementary output signals includes cross-coupled transistors connected to first and second nodes. The first and second nodes are made to be an equal potential by precharging. Then, the potential of the first node is either maintained or changed to a lower (in absolute value) level in response to and dependently on a control input signal, while the potential of the second node is slightly lowered (in absolute value) by dividing the precharged change of the second node with a capacitor. Thus, the first node is controlled by the input signal, while the second node is given a reference potential determined by a capacitance division ratio.
