Abstract

This paper presents a wideband blocker-tolerant RF front-end suitable for direct-ΔΣ-E-receivers. Blockers are attenuated by providing low receiver input impedance at blocker frequencies while for desired frequency the input impedance is boosted to matched condition by providing an up-converted positive feedback from the baseband stage. RF front-end is evaluated on 28nm fully-depleted silicon-on-insulator CMOS process with current consumption of 8mA, excluding local-oscillator drive, at 1V supply voltage. Front-end is reconfigurable from 0.7-3GHz with maximum noise figure of 5dB and achieves an out-of-band 1dB compression point of 0dBm at 100MHz local oscillator frequency offset.
