Abstract :
Low-noise amplifier (LNA) is a very critical component in terms of its functionality in a transceiver. This paper presents design of a 20-GHz low-noise amplifier in TSMC 0.18μm technology. The design utilizes multi-stage topology which includes three transistors. First-stage is a single ended common-source topology while the second stage is current reused topology. Post layout simulations show that the proposed LNA exhibits gain of 14.7dB, noise figure of 3.4dB while it consumes only 10.62mW. Moreover, the chip area of the LNA is 0.5175mm2.
