A 50GHz 130µW inductorless prescaler in 45nm SOI CMOS using ETSPC logic

We present a compact dual-modulus prescaler working at 50GHz without using inductors. A novel divider-by-2/3 in a reduced logic with minimum number of transistors is presented. For the first time, a single-phase clock digital-logic-based prescaler operating at frequencies in the mm-wave band is demonstrated. A power consumption of 130.2µW at 50GHz, gives the best power-efficiency reported. The prescaler is designed in a 45nm SOI CMOS technology with 1V supply.
