| dc.description.abstract | A dual-mode second-order Multirate Multibit Sigma Delta (MM-SD) modulator is implemented in a 90nm digital CMOS process for application in the baseband path of RF receivers. Low power consumption is achieved through a new integrator structure and a dedicated timing scheme along with aggressive capacitor scaling in the second stage of the modulator loop. Fabricated prototype achieves 68.6dB peak Signal-to-Noise and Distortion ratio (SNDR) in the 200 kHz GSM band and requires 1.1mA of total current from a 1.5V supply. This dual-mode design also achieves 42.8dB SNDR in the 1.94 MHz WCDMA band with only 1.9mA of total current consumption. | en_US |
