Wide frequency range voltage controlled transistor relaxation oscillator
TLDR
A VOLTAGE CONTROLLED OSCILLATOR as mentioned in this paper is a VOLUME 7, 2017 VOLUME 6, 2019 VOLUME 5, 2019 OSCLLATOR that provides a controllable output over a wide range from a FEW HUNDREDTHS of a HERTZ to a MEGAHERTZ with a high degree of stability.Abstract:
A VOLTAGE CONTROLLED OSCILLATOR PROVIDING OUTPUT PULSES CONTROLLABLE IN FREQUENCY OVER A WIDE RANGE FROM A FEW HUNDREDTHS OF A HERTZ TO MEGAHERTZ WITH A HIGH DEGREE A ACCURACY AND STABILITY. THE OSCILLATOR EMPLOYS A TRANSISTOR CONSTANT CURRENT SOURCE FOR CHARGING AN ADJUSTABLE R-C TIMING CIRCUIT WHICH TRIGGERS A FEEDBACK CONTROLLED SWITCHING TRANSISTOR CIRCUIT. THE SWITCHING TRANSISTOR CIRCUIT ACTIVATES A SEPARATE TRANSISTOR DISCHARGE CIRCUIT WHICH ALSO SERVES FOR ISOLATING THE TRIGGERING INPUT FROM THE SWITCHING TRANSISTOR DURING SWITCHING TO ALLOW RAPID RESET OF THE TIMING CIRCUIT AND TO IMPROVE THE OUTPUT WAVEFORM.read more

Multi-mode relaxation oscillator
TL;DR: In this article, a relaxation oscillator where the oscillation frequency is proportional to the charge rate of a capacitor, independent current sources are connected through separate switches to change the capacitance of the capacitor and thus the oscillator frequency.
Patent
Regulator for controlling capacitor charge to provide complex waveform
TL;DR: In this paper, the open time of the fuel injector valves was found to change with engine speed by steps not directly related to engine speed, and a regulator system was used to control both increase and decrease of the voltage across the capacitor.
