Abstract
A circuit for detecting and holding the peak voltage of an analog signal is provided. A constant current source controlled by a digital voltage comparator charges a capacitor. The capacitor is charged to a voltage value equivalent to the peak voltage of the analog signal. By selecting the value of the capacitor and the amplitude of the constant current from the current source, slew rate limiting can be achieved, giving the circuit high noise immunity.
