Abstract :
A 0.4mm2 low-power fully-reconfigurable continuous-time (CT) feedforward ΔΣ ADC for 4G radios is implemented in 90nm CMOS. By reconfiguring the topology architecture, quantizer bits, biasing current and component parameters, optimal power consumption can be achieved for every mode. The modulator achieves a DR of 85/78/76/72/58dB for GSM/BT/UMTS/DVB-H/WLAN with 2.8/2.6/3.6/4.9/8.5mW from 1V supply. The FOM is 0.68/0.5/0.28/0.27/0.41pJ/conv.
