Peak-hold circuit and an infrared communication device provided with such a circuit

In a peak-hold circuit, a hold capacitor captures the peak value of an input signal and a reset section carries out a resetting operation on the holding value of the hold capacitor when, upon switching inputs, it receives a reset signal. The reset section, upon receipt of the reset signal, improves...

Summary:In a peak-hold circuit, a hold capacitor captures the peak value of an input signal and a reset section carries out a resetting operation on the holding value of the hold capacitor when, upon switching inputs, it receives a reset signal. The reset section, upon receipt of the reset signal, improves the response speed of a peak-hold section by a predetermined time period. The reset section is provided with a constant current circuit and a switching means for increasing a charging current and a discharging current of the peak-hold section respectively.
