What is an oscillator controlled voltage?
Voltage (VCO) oscillator (VCO) uses the input voltage to determine its oscillation frequency. This may include direct current input (DC) with fixed voltage to form a fixed frequency. The voltage controller can also obtain changing voltage to create an oscillation with a modulated frequency. Some oscillators of this type have a digital pulse output that can produce pulses with modulated width. VCO can be classified as a harmonious oscillator or relaxing oscillator, depending on the type of progress that produces. Harmonic oscillators create progress with sinusoid shapes. This type of oscillator controlled voltage must include an amplifier that would feed the signal back to the input voltage source that creates a resonant frequency that creates a positive gain around the feedback and creates sinusoid waves. A harmonious oscillator may also include a varodite diode that provides part of the capacity of the pro -zonance circuit. The frequency of oscillation can then change according to the input of the voltageThe diodes.
The relaxation oscillator creates a triangular shape. This type of voltage oscillator contains three subtypes, including an oscillator associated with an emitter, an oscillator of a grounded conversation and a delayed oscillator. The amount of time required to charge the capacitor determines the oscillating frequency for an oscillator associated with a grounded and boiling oscillator. The oscillation frequency of the oscillator connected by delay depends on the amount of time needed to make the oscillator any increase in profit.
oscillators of the controlled harmonic voltage have greater frequency stability than relaxing VCOS before noise, power and temperature changes. Frequency control is also better in harmonious VCO, as this type uses a separate circuit for frequency control. The main advantage of relaxation VCO is its ability to be tuned to a wider frequency range than a harmonious type. VCO relaxation is also more suitable for useIts in integrated circuits.
Oscillator The inspected voltage often uses a controller controlled by a voltage capacitor to control the output frequency. This type of capacitor contains a semiconductor diode with a capacity that depends on its voltage. The output frequency of the oscillator can then be controlled by adjusting the input voltage of the diode. The controller controlled voltage is a suitable method of control of the output frequency of high -frequency VCO, as the capacitors of the controlled voltage are easily available in a wide range of capacities. Low -frequency VCO usually uses a power supply of controlled voltage to change the output frequency.
