Non-ideal quantization noise shaping in switched-current bandpass ΣΔ modulators
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the quantization noise shaping of SI BandPass SD Modulators (BPSDMs). Closed form equations are provided for the degradation of the signal-to-noise ratio and for the change…
