Abstract :
A new topology for injection locked frequency divider (ILFD) is proposed to achieve high speed, wide locking range and quadrature phase operation. The dividing mechanism is analyzed and agrees well with the simulation. A prototype is implemented in TSMC 90 nm CMOS and realizes 4 GHz locking range (55.8 GHz-59.8 GHz) with -3 dBm input power and 5 mW DC power consumption. The divider attains the widest locking range with the lowest power consumption to date for V-band frequency dividing applications.
