A 198.9GHz-to-201.0GHz injection-locked frequency divider in 65nm CMOS

An injection-locked frequency divider (ILFD) is realized in 65nm CMOS technology for G-band (140 to 220GHz) applications. Its core area is 0.2×0.16mm
²
. This ILFD consumes 8.8mW from a 1.1V supply excluding the buffers. Due to the limited output power of the source module (i.e., frequency multiplier), the measured locking range of this ILFD is from 198.9GHz to 201.0GHz.
