Abstract :
This paper presents solutions to realize a high-speed, high-precision CMOS timing generator for a 4.266-Gbps memory test system. In order to realize such a timing generator, we developed a 1.066-GHz CMOS timing generator circuit using a high-speed digital delay locked loop circuit and a high-speed, low-INL fine delay circuit. Consequently, we realized a timing generator with 1/20 the size, 4/9 the power, and frac12 the timing error (INL = 8 ps, total jitter =16.8 ps) compared with a conventional timing generator fabricated by the same CMOS process
