Abstract
An indirect analog period synthesis circuit, which can generate a target period from a reference period, is presented. It uses analog switches and an analog delay-locked loop (DLL) to generate a fractional ratio of the input clock. This circuit has been implemented in 0.18 μm CMOS technology using 200 MHz input reference frequency. It can generate the desired period with an acceptable resolution of around 1% and switch from one target period to another in less than 2 μs.
