摘要：
A wideband capacitor cross-coupled common-gate low-noise amplifier (CGLNA) featured with improved linearity is proposed. The linearity is enhanced by complementary multi-gated transistor (CMGTR) technique. The bulk voltage and scaling size are tuned to shift the nonlinear coefficients of auxiliary transistors, compensating the nonlinearity of main transistors. Simulated in a 0.18 [tm RF CMOS process, the LNA achieves a flat voltage gain of 20.2 dB, a noise figure (NF) of 1.62.6 dB, and an input-referred third-order intercept point (IIP3) of 8.910.2 dBm over a 3 dB bandwidth of 0.2-1.6 GHz, respectively. It consumes only 3.5 mA from a 2.2 V supply.
