Abstract 

Comparison of digital and analog figures-of-merit of FinFETs and planar bulk MOSFETs reveals an interesting tradeoff in the analog/RF design space. It is found that FinFETs possess the following key advantages over bulk MOSFETs: reduced leakage, excellent subthreshold slope, and better voltage gain without degradation of noise or linearity. This makes them attractive for digital and low-frequency RF applications around 5 GHz, where the performance-power tradeoff is important. On the other hand, in high-frequency applications, planar bulk MOSFETs are seen to hold the advantage over FinFETs due to their higher peak transconductance. However, this comes at a cost of a reduced voltage gain of bulk MOSFETs.
