8 bit presettable/programmable synchronous counter/divider

The authors describe the design and implementation of an ASIC (application-specific integrated circuit) chip. The design is a J-K flip-flop-based counter. With appropriate control circuitry, this chip can function as a multimode counter/divider subsystem. The device was fabricated using a 5-μm p-well polysilicon-gate CMOS process. It is noted that, due to its versatility, this ASIC has many potential applications.
