Abstract: A divide-by-4 injection-locked frequency divider is designed for applications in the millimeter-wave frequency range. The proposed circuit also features in quadrature phase outputs by using a quadrature voltage-controlled oscillator. The input signal is injected into the common-mode node at the tail current source directly. Implemented in a 0.13 mu m CMOS technology, the core circuit consumes dc power of 3.66mW with 1.2 V supply voltage. The operation range achieves 1.95 GHz. The entire die occupies an area of 974x726 um(2).
