Peak-Detector using Charge Pump and Burst-Mode Transimpedance Amplifier

摘要

The present invention is a peak detection device using charge pumping, a differential amplifier that receives and amplifies a signal to be detected through a positive input node, and controls two or more currents by comparing a signal output from the differential amplifier with two or more reference voltages A current control unit generating signals, a mirror current source including two or more mirror current sources each driven by current control signals generated by the current control unit, and currents output from the mirror current source. And a capacitor charged/discharged by the capacitor, and a reset circuit unit for initializing a voltage of the capacitor.
