摘要： Embodiments of the disclosure provide a peak voltage detection circuit with reduced charge loss. A circuit structure of the disclosure includes a peak voltage detector having a first input node coupled to an input line and a second input node coupled to a first electrically actuated switch. The peak voltage detector coupling the first input node and the second input node to an output node, and a second electrically actuated switch coupling the output node of the peak voltage detector to a capacitor. The first electrically actuated switch couples the capacitor to the second input node of the peak voltage detector. The input line is coupled to a control node of the first electrically actuated switch and a control node of the second electrically actuated switch.
