This paper presents an automatic gain controllable low noise amplifier (AGC-LNA) for FM receiver (FMRx). The proposed LNA adopts current reused dual g(m)-boosting technique for the power saving. And, a simple analog type automatic gain control (AGC) loop is proposed that provides high resolution gain control. Implemented in a 65 nm CMOS technology, measurements show power regulation range of 40 dB with +/- 1 dB error, less than -11 dB of S11, variable voltage gain range of -12 to 30 dB over the frequency range of 88 similar to 108 MHz, noise figure (NF) of less than 2.9 dB, P1dB of higher than -24.2 dBm, and IIP3 of higher than -12.7 dBm in the high gain (HG) mode, while dissipating only 1.8 mA from a 1.2 V supply, respectively.
