Abstract: A 1-V 190-μW delta-sigma modulator with chopper stabilization and bootstrapped switch is designed using a full digital 0.13-μm CMOS technology. The fourth-order feedforward architecture is employed to reduce the output swings of each integrator and relax the DC gain requirement of the operational transconductance amplifier; hence saves power and reduces distortion. The core area excluding PAD is 0.9 X 0.64 mm2. The simulation results show that the modulator achieves 99.8 dB peak signal-to-quantization-noise ratio (SQNR) and -102 dB total harmonic distortions over the 20 kHz signal bandwidth with an OSR of 125. © 2008 IEEE.
