Abstract
This paper presents a digitally controlled RF charge sampling receiver font-end architecture for multiband multi standard RF receivers. A time-varying matching network is proposed instead of traditional ones. The receiver operates in charge domain to produce a band pass Sinc filter centered at the desired local oscillator frequency. A time varying matching network provides tunable matching and selectivity to support multi-bands. This receiver architecture targets LTE band (0.7-2.7) GHz making use of its programmability. Based on a verilogA model, the receiver conversion gain is 33 dB at 2 GHz; the resulting noise figure is 7.3dB, and P1dB and IIP3 of-10dBm are 0 dBm respectively.
