Abstract
Apparatus and associated methods are disclosed for gain programming or selection with parasitic element compensation. In one exemplary embodiment, an apparatus includes a first circuit that has a first programmable gain, and includes a first set of components having parasitic elements. The apparatus also includes a second circuit that has a second programmable gain, and includes a second set of components having parasitic elements. The apparatus has a gain that is a product of the first and second programmable gains. A gain error because of the parasitic elements of the first and second sets of components is canceled by setting the first programmable gain as a reciprocal of the second programmable gain.
