ABSTRACT:
A peak value detecting circuit has a peak voltage holding circuit, a voltage comparing section, a holding voltage control circuit, and a signal output circuit. The peak voltage holding circuit holds a peak value of an input signal voltage. The voltage comparing section compares the peak voltage held by the peak voltage holding circuit with an externally input signal voltage. The holding voltage control circuit controls the level of the peak voltage in accordance with the output given by the voltage comparing section as a result of the compare operation in the latter. The signal output circuit acts as a buffer in sending to the outside the peak voltage held by the peak voltage holding circuit. The output voltage from the signal output circuit is fed back as a reference voltage to a compare input terminal of the voltage comparing section and prevents any offset that may develop in the signal output circuit from appearing in the output signal voltage of the peak value detecting circuit.
