摘要

Recently, continuous-time incremental delta-sigma modulators (CT I-DSM) are increasing in popularity for use in sensor readout applications [1,2] due to their high-resolution and input multiplexing ability. For a modulator to be used with a moderate or low oversampling ratio (OSR) considering the input multiplexing, high-order noise-shaping is required to achieve low noise. A multistage noise-shap...
