Abstract
The invention provides a peak detector having input signal triggering control and low frequency energy attenuation capability. The peak detector includes a charging unit and a discharging unit. By being triggered by a peak value detected in a received input signal by comparing voltage potential levels of the output signal of the peak detector and the received signal, the charging unit charges an electrical charge storage unit, for example, a capacitor, connected to the output terminal of the peak detector for a pre-determined charge duration in accordance with a charge pulse being in a logic high. After the pre-determined charge duration of charging operation, before being triggered by a next peak value of the received input signal, the discharging unit discharges the electrical charge storage unit for a pre-determined discharge duration in accordance with a discharge pulse being in a logic high or in accordance with a plurality of discharge pulses, which is determined by design desired.
