A 56.5–72.2 GHz Transformer-Injection Miller Frequency Divider in 0.13 $\mu{\rm m}$ CMOS

A V-band Miller frequency divider with a locking range of 15.7 GHz (f₀ = 64 GHz) is realized in 0.13 μm CMOS technology. Using the proposed transformer-injection technique, the signal can be injected into the mixer core directly without the current and impedance limitations of the input stage. The divider also features a fully differential topology. Under the condition of V_DD = 0.9 V, the divider can even function with a power dissipation of only 0.81 mW.
