Abstract :
We present the CMOS circuit design and realization of an architecture for synchronizing multiple programmable oscillators (nodes). This circuit performs phase locking and locks to a common frequency with constant phase differences. The nodes are digitally-controlled-oscillators (DCOs) coupled via vector multipliers implemented by composing (analog) CMOS Gilbert multipliers. The overall 3-node example circuit presented here includes on-chip inductors, and occupies total of 712.65mu by 568.2mu area in the 0.5mum technology process. This design is scalable to large numbers of nodes as well as finer feature size technologies
