Abstract 

A 6th order RF bandpass SigmaDelta ADC operating on the 2.4 GHz ISM band is presented. The bandpass loop filter is based on digitally programmable Gm-LC resonators. By using a mirrored-image sampling technique, the clock frequency is reduced to 3 GS/s, thereby reducing the power consumption. Implemented in a standard 90 nm CMOS process, the IC achieves 40 dB and 62 dB of SNDR and SFDR respectively on a 60 MHz bandwidth with 40 mW of power consumption.
