Abstract

In order to support a wide set of communication standards and to accommodate different applications in a single device, broadband receivers are essential and inevitably in demand. A wideband low-noise amplifier (LNA), which is a key block in the design of broadband receivers for multiband wireless communication standards, is proposed. A differential common-gate (CG) LNA utilizing multiple-feedback technique is presented. The multiple-feedback technique adds degrees of freedom in the choice of the LNA transconductance to reduce the noise figure (NF) and increase the amplification. It avoids the use of bulky inductors resulting in considerable area and cost savings. The LNA is designed and simulated in 180 nm CMOS technology. It covers the frequency range of 0.8 GHz to 2 GHz. The designed and simulated LNA delivers a maximum voltage gain of 12.2 dB, a minimum NF of 2.56 dB, a third-order input intercept point IIP3 of -6.5 dBm and 3.6 mW of power consumption with input matching (S11<; -10 dB).
