Summary:In this paper, generalized quadrature bandpass sampling (BPS) in voltage-mode with inherent FIR filtering is presented. By using the theory of sampling equivalence, this sampling strategy is comparable to another strategy, charge sampling with intrinsic IIR filtering. The theoretical analysis and simulation results show that this inherent FIR filtering not only has the advantage of rejecting or attenuating images and interference, but is also helpful in suppressing noise aliasing. A realizable implementation of the proposed sampling strategy by uniform quadrature BPS (UQBPS) promises to suppress noise aliasing in BPS systems to a large extent.
