Abstract
An injection-locked frequency divider for dividing a frequency of an injection signal and obtaining a frequency divided signal is provided. The injection-locked frequency divider includes a signal injection unit and an oscillator. The signal injection unit includes a first input terminal and a second input terminal for receiving the injection signal. The received injection signal exhibits a phase difference of 180° between the first input terminal and the second input terminal. The oscillator includes an inductor unit and a variable capacitance unit. The injection-locked frequency divider is featured with a wide injection locking range, and can be realized with a low operation voltage, and therefore can be conveniently used in different kinds of hybrid ICs.
