| Abstract | This paper presents a discrete-time (DT) 4-order ∆Σ modulator using a 2-order noise-shaped integrating quantizer (NSIQ). By adding a passive finite impulse response (FIR) filter to the 1-order NSIQ, the proposed quantizer has obtained 2-order noise shaping ability, without extra power consumption. By incorporating the digital integrator, the linearity requirement of the quantizer is relaxed. The proposed modulator is fabricated in a 0.18 µm CMOS process, and operates at 1 MS/s achieves a peak signal-to-noise-and-distortion ratio (SNDR) of 106.9 dB in a 10 kHz bandwidth while consuming 240 µW with 1.8 V power supply. |
