Abstract
A phase-locked loop provides an output frequency, locked to a multiple N of a reference frequency, responsive to a frequency-control voltage supplied to the output-frequency-generating voltage-controlled oscillator from the output of a differential amplifier. The differential amplifier inputs are provided with voltages sampled from the output of a pair of integrators respectively enabled for integration during complementary, and substantially identical, portions of the phase detector output waveform. Output-frequency-control voltage ripple is substantially reduced, with concomitant reduction of frequency modulation of the output freqeuncy, over the reference frequency period.
