Beschreibung
Zusammenfassung:	A technique for reducing input currents associated with a comparator circuit (30) during certain events includes minimizing bias currents associated with the comparator circuit (30) when a magnitude of an input signal (VIN) at a signal input of the comparator circuit (30) is a predetermined value from a magnitude of a reference signal (VREF) applied to a reference input of the comparator circuit (30). The bias currents are increased when the magnitude of the input signal (VIN) is within the predetermined value of the magnitude of the reference signal (VREF).
