ABSTRACT:
A peak detector can advantageously increase its bandwidth, i.e. its charging and discharging speed, while minimizing the ripple of its output signal by sensing the charging current of a storage device. In response to that charging current, the peak detector can control a discharge current, thereby accelerating its response. For example, the peak detector can reduce a discharge current in response to an increased charging current (which indicates a charging phase) and increase the discharge current in response to a decreased charging current (which indicates a discharge phase).
