Abstract
Verniers are provided that substantially eliminate DC offset signals as they convert a differential input signal S to a differential output signal S with a conversion gain that corresponds to a digital command signal. The verniers are especially suited for use with multiplying digital-to-analog converters (MDACs) in communication systems. An exemplary use is forming line drivers to drive load impedances (e.g., coaxial cables).
