We have implemented a 65nm CMOS Epsilon Delta modulator with 94dB Dynamic Range (DR). The power dissipation is 407umW in a 500kHz signal bandwidth under a 1.2V power supply voltage. This design proves that the feedforward Epsilon Delta topology is an excellent topology for low-power, high bandwidth and high resolution Epsilon Delta ADC designs in nm CMOS technologies.
