A 2 GHz bandpass analog to digital delta-sigma modulator for CDMA receivers with 79 dB dynamic range in 1.23 MHz bandwidthIEEE Journal on Solid State Circuits
AbstractThis paper presents the design of a second-order single-bit analog-to-digital continuous-time delta-sigma modulator that can be used in wireless CDMA receivers. The continuous-time delta-sigma modulator samples at 2 GHz, consumes 18 mW at 1.8 V and has a 79-dB signal-to-noise ratio (SNR) over a 1.23-MHz bandwidth. The continuous-time delta-sigma modulator was fabricated in a 0.18- m 1-poly 6-metal, CMOS technology and has an active area of approximately 0.892 mm2 . The delta-sigma modulator's critical performance speciﬁcations are derived from the CDMA receiver speciﬁcations.
