Abstract
The phase comparator in a phase locked loop synthesizer has a identical first and second transmission gates connected to a front row and a back row of 2N−1 gate delay elements, respectively. Third and fourth transmission gates are permanently set to an ON setting. The first transmission gate and NAND gates operate as a gate delay element when a COUNT signal is at a low logical level and operate as a ring oscillator when the COUNT signal is at a high logical level.
