A 1.5-V Power Supply inductorless Low Noise Amplifier with 1dB-STEP programmable gain for FM-Radio receivers

Abstract

In this paper a Low Noise Amplifier suitable for usage in FM-Radio receivers in a standard 60 nm RF process is presented. The LNA is designed to be used without a matching network in order to minimize the PCB cost, which means that the input impedance is in accordance with the antenna impedance. The LNA has a total gain of 27 dB, programmable in 1 dB-step, in the FM-Radio bandwidth. The noise figure of the LNA is 2 dB, its P1dB is −27 dBm and the current consumption is 3mA.
