Design of Ultra Wideband CMOS Low–Noise Amplifier using ResistiveS hunt–Feedbackپانزدهیمن کنفرانس مهندسی برق ایران

In this paper an ultra–wideband (UWB) CfuIOS low noise amplifier (LNA) topologt that combines a narrowbancl LM with a resistive shuntfeedback
is proposed. The resistive shr.mt–feedback provides wideband inpr.i matching with small noise fgure (NF) degradation by reducing the Q–factor of the narrowband LNA inpttt and by flattening the pass–band gain. The proposed UWB amplifier is implemented in 0.l8pm CIUIOS technology for 3 1–10 6–GHz with a supply voltage of 1.8V. Simulations show a –3–dB gctin bandwidth of 3.5–10 GHz, a minimttm NF of 2 2 dB, a power gain of 12.2 dB, and a power dissipation of 23 4 mW.<\div>
