Abstract :
An improved high-performance dynamic-logic tristate phase-frequency detector architecture is derived through extensive time domain analysis. In particular, the impact of the reset time´s on the maximum operating frequency and phase characteristics of the phase-frequency detector is discussed. The analysis is verified for the presented improved architecture and excellent agreement between theory and simulation is observed. The phase-frequency detector architecture is proven to function for supply voltages below 1 V and has an increased frequency capability of more than 20% with a power consumption of 10 μW at 500 MHz input frequency.
