  • Abstract
    A 0.1–0.7GHz switched-capacitor RF front end features tunable center frequency and programmable filter order as well as very high tolerance for out-of-band (OB) blockers. RF input impedance matching, N-path filtering, down-conversion, and high order IIR filtering are implemented using highly linear switches and capacitors only. The 3.24mm2 40nm CMOS front-end prototype consumes 38.5–76.5mA, achieves 24dBm OB-IIP3 and 14.7dBm B1dB for a 30MHz offset, 6.8 to 9.7dB NF, and >66dB calibrated harmonic rejection ratio.
