A Pseudo-Pseudo-Differential ADC Achieving 105dB SNDR in 10kHz Bandwidth Using Ring Amplifier Based Integrators

This brief presents a high-resolution ADC which makes use of the pseudo-pseudo-differential noise filtering technique in an oversampling ADC architecture with ring amplifier based integrators. The pseudo-pseudo-differential noise filtering technique utilizes single-ended circuits while maintaining the even-order rejection found in fully-differential structures which alleviates, in the active analo...
