Abstract
Embodiments of the present invention provide an approach for utilizing a sense amplifier to select a suitable circuit, wherein a suitable circuit generates a voltage that is greater than or equal to a configurable reference voltage. An amplifier gain selector selects a voltage gain of a sense amplifier having input terminals, auxiliary inputs, an output, an array of resistive loads, and the amplifier gain selector. Auxiliary inputs are utilized to nullify direct current (DC) offset voltage of the sense amplifier. Combinatorial logic circuitry connects the input terminals of the sense amplifier to output terminals of a circuit that is within a group of circuits. A comparator circuit determines if the circuit generates a voltage greater than or equal to a configurable reference voltage, based on the output of the sense amplifier.
