This paper presents a wide operation range 0.18mum CMOS frequency divider for 60GHz wireless applications. The direct injection lock technique is used to perform the signal division at millimeter-wave frequency. The deep n-well is implemented under the NMOS switch transistor to improve the lock range of the frequency divider. Combined with band switching and analog frequency tuning, the operation range of the frequency divider covers from 43 to 49 GHz. Operated at 1V, the frequency divider consumes 8mW of power. The core circuit of the frequency divider occupies 200mum times 320mum of silicon estate
