Modification of phase-locked-loop performance using a sample-and-hold circuit
Abstract
The inclusion of a sample-and-hold circuit between the lowpass filter and the VCO of a phase-locked loop allows control over the time period when the loop is locked to the input voltage. This technique has potential in phase measurements, demodulation techniques, phase radar and spread-spectrum communications.
