Latest Patents

Jui-Cheng Han holds a patent for an "Injection-locked frequency divider embedded an active inductor." This invention provides an injection-locked frequency divider that includes an active inductor unit, a source injection unit, a first transistor, and a second transistor. The device generates a frequency-divided signal that has a half frequency of the signal source. The locking frequency range of this divider is determined by the quality factor of a resonant cavity. Notably, the quality factor of the active inductor unit is lower than that of a conventional spiral inductor, as it is composed of active elements. By utilizing the active inductor unit instead of a conventional spiral inductor, the chip area can be reduced, and the locking frequency range can be increased. Furthermore, the induction value of the active inductor unit can be altered to change the locking frequency range of the injection-locked frequency divider.
