Abstract
A divide-by-1/1.5 divider cell using a dual edgetrigger technique is proposed. Based on this divider cell, a dual-mode programmable divide-by-X circuit is demonstrated in 0.18-μm CMOS technology, where X = P or P.5 in one mode and 2P or 2P+1 in the other mode with P = 128-255. When operated in the divide-by-IP/2P+1 mode, this circuit outputs a signal with 50% duty cycle. Theoretically, P can be any arbitrary and programmable integer. © 2005 IEEE.
