Abstract

In this paper, a high-bandwidth low-noise amplifier using gm-Boosting technique and noise cancellation method is presented. In this design, the common gate and input auxiliary amplifier are used in the input stage as the gm-Boosting, and the second stage is used to improve the gain and eliminate noise. This amplifier is designed with a 0.18μm CMOS technology, simulation results illustrate the voltage gain of 17.5 ± 1.5 dB at 2.2 to 12.2 GHz bandwidth, s11
