摘要： A peak hold circuit includes an input transistor, which is provided with an input signal, and a first hold capacitor, which holds a maximum or minimum value of the input signal. A correction circuit, which corrects the hold voltage held by the first hold capacitor, includes an operational amplifier, which is supplied with the hold voltage, and a correction transistor, which is provided with an output signal of the operational amplifier. A source/emitter of the correction transistor is coupled to the operational amplifier. The peak hold circuit also includes a current detection circuit, which detects current flowing to the input transistor, and a peak current hold circuit, which holds the peak value of the current detected by the current detection circuit as a peak current and supplies the peak current to the correction transistor.
