Abstract
Systems and techniques relating to voltage signal peak level detection used in sensor devices, namely in Fly-Height Sensors (FHS) devices include, according to an aspect, an integrated chip device comprising: peak detection circuitry configured to receive a voltage signal and output a peak voltage signal associated with a peak voltage level of the voltage signal, wherein the peak detection circuitry comprises: a linear loop section configured to store the peak voltage level and hold additional voltage levels of the voltage signal at an output terminal of an amplifier to a value greater than zero; and a feedback loop section configured to reduce a leakage current within the peak detection circuitry and generate a guard voltage signal usable to reduce a feedback voltage and prevent the feedback voltage from successively re-entering into the feedback loop section.
