Abstract
A circuit for facilitating random edge injection locking of an oscillator comprises a clock signal and a digitally controlled delay line, where the digitally controlled delay line is configured to delay the clock signal, thereby generating a delayed clock signal. The circuit further comprises an edge selector configured to generate a phase select signal with a random pulse sequence. Moreover, the circuit comprises a pulse generator downstream to the digitally controlled delay line configured to generate injection pulses from the delayed clock signal for at least two phases of the oscillator based on the phase select signal.
