Abstract
Since an ever-unrevealed shortcoming in dynamics was reported for phase-locked loops, two alternative arrangements have been proposed. This paper describes another novel configuration without a seperate phase comparator, making use of the linear time-voltage characteristics of ramp waves inside VCO's. In addition to requiring fewer circuit components, normalizing the loop gain can yield time-optimal responses without overshoots. Other features include the normal FM detection capability and unconstrained input for time-optimal operations. Implementation requires less than 10 IC's, providing the operating frequency range of 0.01Hz to 100kHz. A prototype demonstrated the above advantages.
