摘要

The /3 and /5 regenerative frequency dividers (RFDs) with ultra-wide locking ranges are presented. The proposed dividers were fabricated by a TSMC 90 nm CMOS process, using /2 and /4 quadrature-injected current-mode-logic loop dividers to widen the locking ranges. The dividers also achieved quadrature input and quadrature output. Using a 1.2 V supply voltage, the power consumptions of the /3 and the /5 divider cores were 10.2 and 14.8 mW, respectively. Without using the tuning techniques, the measured locking ranges for the /3 and the /5 dividers were from 9 to 14.7 GHz (48.1%) and 7.2 to 19 GHz (90.1%), respectively. The phase deviation of the quadrature outputs for the two dividers were less than 0.8° and 1.1°. Compared with the reported data, the outstanding figure-of-merit values of the proposed /3 and /5 RFDs can be observed.
