Abstract
This paper reports on a system level design and analysis of a mash fourth-order sigma-delta (ΣΔ) modulator. Compared with a high-order single-loop ΣΔ modulator (ΣΔM), there’s no need to consider about the system stability of a mash ΣΔM, which has the advantages of better signal to quantization noise ratio (SQNR). System level simulation results indicate that the SQNR is 122.0 dB, and the effective number of bits (ENOB) is 19.97 bits when the over sampling ratio (OSR) is 128.
