ABSTRACT:
A transient noise free type amplifier circuit includes a first amplifier having a noninverting input to which an input signal is applied, and a first output. An inverter inverts the input signal and supplies the inverted signal to a second amplifier having a signal input to which the inverted signal is applied, and a second output, and which second amplifier provides the same amplification as the first amplifier. A bias circuit supplies a predetermined bias potential to bias inputs of the first and second amplifiers, and a resistor circuit supplies the bias potential to the signal input of each of the inverter and the first amplifier. An output siganl which corresponds to the potential difference between the first output of the first amplifier and the second output of the second amplifier, is thus provided.
