Abstract:	Abstract— This paper demonstrates a low-jitter clock multiplier unit [1] that generates a 10 GHz output clock from a 2.5 GHz reference clock. An integrated 10 GHz LCoscillator is locked to the input clock, using a simple and fast phase detector circuit. This phase detector overcomes the speed limitation of a conventional tri-state Phase Frequency Detector, by eliminating an internal feedback loop. A frequency detector guarantees PLL locking without degenerating jitter performance. The clock multiplier is implemented in a standard 0.18¹m CMOS process and achieves a jitter generation of 0.22 ps while consuming 100 mW power from a 1.8 V supply.
