Abstract
We present an injection-locked divider (ILFD) with a double-balanced structure to generate two signals with tunable phase difference. A circuit prototype was designed and fabricated using a standard 0.18mum digital CMOS technology, and generates dual-phase signals at 4.8-6 GHz. The phase difference of the two output signals can be tuned independently by 55deg, and differentially by 100deg, both centered around quadrature (90deg). The phase noise degradation is negligible
