  • Comparison of digital and analog figures-of-merit of FinFETs and planar bulk MOSFETs reveals an interesting trade-off in analog/RF design space. It is seen that FinFETs possess key advantages over bulk FETs for applications around 5 GHz where the performance-power trade-off is important. In case of higher frequency applications bulk MOSFETs are shown to hold the advantage on account of their higher transconductance (Gm), provided a degraded voltage gain and a higher leakage current can be… CONTINUE READING
