Recent advances in Gain-Bandwidth trade-off for Ultra-Wideband 45-nm CMOS Low-Noise Amplifiers (LNAs)

In present day society where communication technologies are advancing at spiral rate, the need for efficient integrated circuit design to transmit and receive signals at unlicensed frequency spectrum is inevitable. This study tries to shed new light on the latter topic by evaluating the issues associated with the design in advanced CMOS technologies of a critical RF building block, namely a single stage differential low-noise amplifier (LNA) for ultra-wideband (UWB) applications At receiving front end, the low noise amplifier design, being the first building block to receive the signal puts a tremendous challenge on modern day radio frequency engineers to meet real world problems involving trade-off in design issues. In this paper the gain-bandwidth trade-offs are streamlines in concurrence to Ultra Wide Band (UWB) radio transmission spectrum.
