PURPOSE:To obtain the output corresponding to the input signl by providing the capacitor between the input sides of the reverse and non-reverse amplifier circuits and the input terminal and then giving the decision to the input signal featuring a small input signal at a certain level. CONSTITUTION:Reverse amplifier circuit 81 and non-reverse amplifier circuit 82 share input terminal 10, and bias circuit 80 decides the DC bias voltage for circuits 81 and 82. Gate group 83 operates with reception of the output of circuits 81 and 82, and capacitor 70 is inserted between the input sides of circuits 81 and 82 and the input terminal. In such constitution, the input signal featuring a small amplitude is decided at a certain level, thus obtaining the output corresponding to the input signal. |
