This paper presents the design and simulation of a CMOS ultra-wideband low noise amplifier. The amplifier exhibits a form of thermal noise canceling with a shunt-feedback topology for operating in the band of 100-960 MHz. It was designed using the AMI C5F/N (0.5 mum) process. Thorough simulations including anticipated parasitics predict a noise figure ranging from 1.84-2.45 dB, a forward gain of 11...
This paper presents the design and simulation of a CMOS Ultra-wideband Low noise Amplifier. In the design, specific architecture decisions were made in consideration of system-on-chip implementation. The basic architecture of the LNA designed herein exhibits a differential amplifier core with active input and output impedance matching. Simulations reveal that the LNA maintains a gain of 16.7 dB with...
Ultra-wideband (UWB) is a promising new technology with great potential for short-range ultra-high-speed wireless communication systems. In this paper, a low noise amplifier (LNA) with broadband matching using a resonant circuit that has excellent gain flatness in the frequency range of 3 GHz to 6 GHz is designed for UWB applications. The TSMC 0.18 mum RF CMOS technology was used for simulation. Thus...
