Message 3 of 7. The 2SC appears to be an older component and may be hard to come by sim and layoutbut there are several medium power transistor replacements that might work and there are several available in the Multisim database.

An opamp VCO circuit is shown in the LM opamp datasheet, and that’s the basis for the design shown here. Does this affect the frequency change you observe in any way? The circuit diagram of dafasheet voltage controlled oscillator using LM is shown in the figure below.

Figure 4 – Diode Sinewave Shaper. He asked for LM not LM Commercial use is prohibited without express written authorisation from Rod Elliott. Thank u very much. Message 6 of 7.

You may also like: The control voltage input needs to be biased to some voltage that gives you the base frequency you need. The main claim to fame is that it is a low power IC, and has an input range that includes the datashedt supply rail – the input voltage can go below the negative supply by up to mV or so, and the output can swing to within a few millivolts of the negative rail. The circuit relies on feedback, and even a seemingly trivial error will stop it from working.

Message 1 of 7. If you only need a low frequency VCO, this is the easiest way to build one. If you want to build eatasheet of the circuits shown, you’ll need to use Veroboard or similar. This will change slightly depending on the load and the ICs internal temperature.

The author Rod Elliott grants the reader the right to use this information for personal use only, and further allows that one 1 copy may be made for reference while constructing the project. This is the frequency obtained when there is no external modulation.

This may seriously affect the transistor’s performance. Can you recommend a circuit l566 teach me how to do this?

You can also change datashheet resistors around the input stage or the Schmitt trigger. Previous post Next post. VCOs are used for tone generators, frequency modulators, clock generators, function generators, music synthesisers and frequency shift keying FSK, a radio transmission system where digital om566 is transmitted via discrete frequency changes of a carrier wave.


Thus by varying the voltage across the varicap diode in the tank circuit, the output frequency of the VCO can be varied.

Voltage Controlled Oscillator (VCO)

Further, your statement is incorrect- the control voltage must be less than a maximum. The frequency change is related to the amplitude, and the rate-of-change is determined by the modulation frequency. Fully temperature compensated circuitry is required if you need a precision VCO, and if that’s what you need then this general class of VCO is not suitable.

Capacitor C2 is used to prevent the parasitic oscillations during VCO switching. I’ve included it here purely for the sake of completeness and to show how easy it was to dztasheet a VCO a few years ago.

VCO Voltage controlled oscillator Voltage controlled oscillator vatasheet a type of oscillator where the frequency of the output oscillations can be varied by varying the amplitude of an input voltage signal.

Greater frequency range is possible with careful design. Message 4 of 7. Other constraints are the values of Rt and Ct those determine the output frequency range.
