A LOW-POWER WIDEBAND CMOS LOW-NOISE AMPLIFIER USING CURRENT-REUSE TECHNIQUE

摘要

A CMOS low noise amplifier (LNA) for low-power ultrawideband wireless applications is presented. To achieve low power consumption and wide operating bandwidth, the proposed LNA uses a currentreused technique and a simple high-pass input matching network. This work is implemented in 0.18-μm CMOS process technology and shows a 3.1- 10.6 GHz bandwidth. With only 1.5 V supply voltage, the LNA can achieve power flat gain of 13.2 dB with input matching of -10.3 dB, the minimum noise figure of 3.33 dB, and input third-order-intercept point (IIP3) of -3.3 dBm. The power dissipation is only 9.3 mW.
