Abstract :
A design technique for multitap c.c.d. delay lines is discussed in which the effective charge transfer efficiency is increased over its intrinsic process-dependent value. The technique involves locating tap amplifiers at every alternate bit, and operating the device at twice the normal clock rate. The advantages of the technique are discussed with reference to a 32-tap, n-channel c.c.d. delay line.
