Abstract
A harmonic injection-locked frequency divider for high-speed applications is presented in this letter. In order to enhance the bandwidth of the high-order frequency division, a positive feedback is employed in the design of the subharmonic mixer loop. The proposed circuit is implemented in a 0.18-μm SiGe BiCMOS process. With a singled-ended super-harmonic input injection of 0dBm, the frequency divider exhibits a locking range of 350MHz (from 59.77 to 60.12GHz) for the divide-by-four frequency division while maintaining an output power of -16.6/spl plusmn/ 0.5dBm within the entire frequency range. The frequency divider core consumes a dc power of 50mW from a 3.6-V supply voltage.
