<p>An amplifier in which the feedback impedance includes a four terminal capacitor, and in which the input impedance is connected to a source of operating potential. The use of a four terminal capacitor as a feedback element compensates for the failure mode of the amplifier in which the opening of the feedback element results in infinite AC gain of the amplifier. The connection of the signal input impedance to a source of operating potential compensates for the failure mode of the amplifier in which the input impedance shorts, which normally results in infinite AC gain of the amplifier.</p> |
