Multiphase output oscillator
TL;DR: In this paper, a multiphase output oscillator is organized in a loop, where each oscillator circuit is coupled to its serial successor in the loop, to provide adjustment of the phase of an oscillation signal of the successor oscillator circuits dependent upon a difference between the phases of the oscillation signals in the successor and the phases in the particular oscillator signals.

Frequency modulated phase-locked oscillator having a low- and high-frequency response
TL;DR: In a phase-locked loop frequency modulator, the signal applied to the reference input of the phase comparator is a frequency-modulated signal, modulated at the same rate as the output signal, for low-modulating frequencies as discussed by the authors.
Patent
Frequency synthesizer having plural phase locked loops
TL;DR: In this article, a first phase locked loop (PLL) having a second PLL with programmable divider therein supplying 50 kilohertz steps of coarse tuning to a mixer and a third PLL having programmable dis-interference for providing any of a plurality of steps of frequency within a band of frequencies in response to control signals applied to the two programmable dividers.
Patent
Wide range drift compensated FM signal generator
TL;DR: In this paper, the output frequency of a variable frequency oscillator is compared with that of a reference frequency source by means of a phase detector and the resultant error signal is integrated and applied as a negative feedback signal to the input of the oscillator whereby drift of oscillator output frequency is minimized.
Patent
Phase locked loop frequency synthesizer and frequency modulator
TL;DR: In this article, a frequency-modulated electrical signal generator comprising two oscillators, the first delivering a modulated output frequency and driving a mixer which receives in addition the output of the second oscillator.
