Abstract
A signal integrator stabilization circuit comprises an operational amplifier functioning as a comparator. The circuit further comprises an attenuator in the amplifier's feedback, thereby generating a feedback signal which is sampled to produce a sampling signal. The integrator is driven with a preselected ratio of the feedback signal and the sampling signal to produce a stabilized output signal approaching a zero value which has a good DC stability without compromising the ability to accurately integrate high frequency signals.
