Abstract: A MOS device includes a set of pMOS transistors on a first side of an IC. The set of pMOS transistors is adjacent to each other in a second direction. The MOS device further includes a set of nMOS transistors on a second side of the IC. The set of nMOS transistors is adjacent to each other in the second direction. The second side is opposite the first side in a first direction orthogonal to the second direction. The MOS device further includes an OD region between the set of pMOS transistors and the set of nMOS transistors. A first set of gate interconnects may extend in the first direction over the OD region. A set of contacts may contact the OD region. The OD region, the first set of gate interconnects, and the set of contacts may form a set of transistors configured as dummy transistors or decoupling capacitors.

Each pass-gate transistor is coupled between one of the differential inputs of the latching circuit and a corresponding differential input of the sampling circuit.

Abstract: Systems and methods for dividing input clock signals by programmable divide ratios can produce output clock signals with the delay from the input clock signal to the output clock signal independent of the value of the divide ratio and with the duty cycle of the output clock signal being 50% independent of the value of the divide ratio. An example programmable clock divider includes a modulo N counter that produces a count signal that counts modulo the divide ratio and a half-rate clock signal generator that produces a common half-rate clock signal, an even half-rate clock signal, and an odd half-rate clock signal that toggle at one-half the rate of the output clock signal. The common half-rate clock signal, the even half-rate clock signal, and the odd half-rate clock signal are combined to produce the output clock signal.
