An electronic vernier realizes programmable gain steps with first and second impedance ladders, a plurality of activatable coupling networks and a switch network. The ladders receive and progressively process the differential input signal into a plurality of progressive differential signals. In an embodiment, the coupling networks each generate a respective one of a plurality of progressive differential output signals in response to a respective one of the progressive differential signals and the switch network activates any selected one of the coupling networks. Thus, any selected vernier step is obtained by activating the respective coupling network. The verniers can be integrated into various systems, e.g., programmable amplifiers.
