An NS-SAR Quantizer-Based Pipeline Incremental Delta-Sigma ADC Using a Current-Regulated Floating Ring Amplifier and Two-Phase Miller Negative-C

Abstract: A pipeline incremental ADC (IADC) leverages a 6-bit noise-shaping SAR quantizer for high SQNR at low OSR. A pipeline IADC structure enables continuous sampling and concurrent stage ...
