24.6 A Time-Interleaved Filtering-by-Aliasing Receiver Front-End Achieving >70dB Suppression at <4×Bandwidth Frequency Offset
DOI:
https://doi.org/10.31224/2178Abstract
The Filtering-by-Aliasing (FA) approach uses a sampled integrate-and-dump circuit with an appropriately chosen periodically time-varying resistor, R(t)=R(t+Ts), to realize an equivalent FIR filter with desired impulse response, g(τ). This work applies time-interleaving to increase the length of g(τ) to 2Ts and so achieves Astop>70dB without sacrificing filter sharpness, linearity, S11, or NF.
