Abstract

Optimizations of 0.18 μm and 0.5 μm MOSFET amplifiers without using inductors for UWB applications are presented. A 3 dB bandwidth from 3.1 GHz to 9.9 GHz with minimum 9.6 dB of transducer gain at 10.6 GHz and approximate 92.8 mWatts of total power consumption are achieved. The source and load impedances were 50 ohms. Also, the number of capacitors and resistors has been minimized. To predict characteristics more precisely, the pad capacitance is added to the output port. In addition, a different feedback topology is presented which gives a lower Noise Figure with maximum 7.73 dB at 10.6 GHz with 300 ohms feedback resistance.
