A 1.5 GHz Fully Monolithic CMOS LNA and Its Noise Behavior
A 1.5 GHz Fully-Monolithic CMOS LNA and Its Noise Behavior Arif Mahmud, Samir El-Ghazaly Arizona State University, Tempe, AZ, USA arif@asu.edu sme@asu.edu Abstract A 1.8 V, 1.57542 GHz LNA has been designed for a 0.5-µ m CMOS process. This amplifier provides a forward gain of 19 dB with a low noise figure of only 2 dB while drawing 17 mW DC power. Unlike most of the circuits in literature, this d
