Analysis and implementation of uniform quadrature bandpass sampling
Sampling noise folding causes a large SNR degradation at the output of bandpass sampling (BPS) system. A sampling architecture based on generalized quadrature bandpass sampling (GQBPS) was proposed in Y.-R. Sun and S. Signell (2005). Theoretical analysis showed that such architecture is promising to reduce the SNR degradation due to noise aliasing. In this paper, uniform quadrature bandpass sampling (UQBPS) as a special case of GQBPS is analyzed for both ideal sampling and a sample-and-hold. One available implementation method to UQBPS is shown and discussed at the circuit level.
