摘要：

In this paper, a 110 dB, 1.024 MHz fourth-order single-loop sigma-delta modulator has been presented with an over-sampling ratio of 128 and an overload factor of -6 dB for a bandwidth of 4 kHz. In particular, this Sigma-Delta modulator is well suited for atmospheric pressure sensor. The whole modulator consumes only 3-mW from a single 3.3V supply in a 0.35-mu m CMOS technology and chip size is 1.68 mm(2).
