Abstract :
A single-loop second-order 3 bits ΔΣ modulator in 180 nm standard CMOS is presented. The design is intended to achieve high linearity in low-voltage low-power environment. The modulator achieves 89-dB SNDR and 98-dB SFDR in 20Hz~16kHz signal bandwidth, while the power consumption is 210 μW under 1-V supply voltage.
