Abstract:
Self-injection has been used in lasers and photonic integrated circuits to reduce the laser’s phase noise (PN). We show that self-injection can be leveraged in GHz LC oscillators as well. Our oscillator employs a current-domain self-injection technique by leveraging second-harmonic extraction, capacitive phase shifting, and self-mixing through the oscillator’…
