Abstract

This paper presents a -88 dBm sensitivity, 150Kbp/s OOK mixer-first nonlinear receiver in 65nm CMOS operating at the 2.46GHz ISM band. Since the LNA in the 1^st IF band can be saturated by the strong in-band interferer, the shifted limiter (SL) is used to improve the interference resilience. Hence, by using an input power detection block, the 1^st gain stage in the 1^st IF band can alternatively turn on the LNA or the SL to improve the dynamic range. The in-band SIR at +/-1, 3 and 5MHz are measured to be -43/-11, -53/-54 and -53/-56dB respectively, while just consumes 380 to 610μW.
