Abstract :
This work proposes an inductorless wideband low noise amplifier (LNA) for multistandard applications. This LNA is based on a self-biased complementary current-reuse common source amplifier on the forward path and a source follower on the feedback, using a gyrator-C like effect to create real valued impedance and an inductive effect, achieving wideband input matching. Designed in IBM 130 nm CMOS process, it presents NF of 2.7 dB, voltage gain of 22.8 dB, IIP3 of -6 dBm. The power consumption is 2.8 mW for a supply voltage of 1.2 V.
