    Abstract

    A 120 GHz voltage controlled oscillator (VCO) with a divider chain including an injection locked frequency divider (ILFD) and six static frequency dividers is demonstrated using 65-nm CMOS technology. The VCO is designed based on the LC cross-coupled push-push structure and operates around 120 GHz. The 60 GHz ILFD at the first stage of the frequency divider chain is based on a similar topology as the core of the VCO to ensure the frequency alignment between the two circuit blocks. The static divider chain is composed of D-flip flops, providing a 64 division ratio. The entire circuit consumes a DC power of 68.5 mW with the chip size of 1385 × 835 μm2.
