Correlated Dual-Loop Sturdy MASH CT ΔΣ ADC with Indirect Signal Feedforward

The demand for continuous-time (CT) $\Delta \Sigma$ modulators (DSMs) to achieve high dynamic range (DR) for wide bandwidth (BW) modern wireless applications is never-ending. Using a large oversampling ratio or employing multibit quantizer lowers the in-band quantization noise (QN) with the sacrifice of increased power consumption and circuit complexity. Increasing the order of the loop filter is ...
