A 85dB-SNDR 50 kHz bootstrapping-free resistor-less SC Delta-Sigma modulator IP block for PVT-robust low-power ADCs

This paper presents a switched-capacitor Delta-Sigma modulator (ΔΣM) IP block for low-power high-resolution ADCs. The ΔΣM IP proposal does not require any circuit calibration, internal supply bootstrapping nor resistors. A complete design methodology from architecture to CMOS circuit levels with spe...
