Abstract :
In this paper, we propose and quantitatively evaluate an “All-Graphene nano-ribbon (GNR) circuit” for high frequency low noise amplifier (LNA) applications, which shows considerable advantage over state-of-the-art technologies. In particular, we discuss how to satisfy the requirements for temperature stability, gain, power dissipation, noise and speed for a high performance LNA circuit by adjusting only the width of the nano ribbons. Our calculations predict a nano-ribbon width in the range of 8-12 nm to be ideal for these types of applications - different from logic applications that are expected to require much smaller ribbon widths.
