Abstract

This paper presents a mult i-phase sub-harmonic in- jection locking technique. This technique can signiﬁcantly increase the locking range of a multi-phase i njection locking oscillator com- pared to the conventional single-phase injection locking scheme. By application of this technique, a scalable “active frequency mul- tiplier” chain architecture is proposed, which can generate THz signal from a low mm-wave frequency or RF reference source. We also propose a multi-ring system topology to imple
