A 550µW inductorless bandpass quantizer in 65 nm CMOS for 1.4-to-3GHz digial RF receivers

摘要

This paper presents an inductorless clockless RF bandpass quantizer in a standard 65nm CMOS technology. An entirely new approach is used based on the information sign and envelope of the RF signal. The quantizer achieves a SNDR of 34dB for an 80MHz bandwidth within a frequency range of 1.4 to 3GHz while consuming 550µW and occupying 0.04mm². A FOM of 64fJ/conv is a 45-fold improvement over previous art.
