This is engineering, not poetry. The circuits aren’t critical, but I do recommend that you datasheer a nF ceramic capacitor as close as possible to the IC supply pins. C1 is selected to give response down to the lowest frequency of interest, and is less than 1. The output voltage may be stuck at zero or around 10V. A voltage controlled oscillator VCO isn’t something datasheeh need every day, and you may never have thought that you need one at all.

Also your link is to the but your title and text says Another application of the voltage controlled oscillator is the variable frequency signal generator itself. Message 5 of 7. A positive modulation voltage causes the frequency to increase, and vice versa. datzsheet

See below for the diode clipping circuit. If you only need a low frequency VCO, this is the easiest way to build one. As shown, four diodes are used to clip the triangle wave in such a way as to get minimum distortion.

The circuit relies on feedback, and even a seemingly trivial error will stop it from working. Relaxation-type voltage controlled oscillators are used to produce a sawtooth or triangular waveform. You’d probably be right, but some things are just too interesting to ignore, and this is one of them. If the modulation input is referred to ground e. Post as a guest Name.

The control voltage input needs to be biased to some voltage that gives you the base frequency you need. The output frequency vs.

The frequency of the output waveform can be adjusted using an external control datsaheet. Message 4 of 7. Is your intent just simulation or do you want datashedt lay out a PCB? While the LM is quite ok for a fairly basic VCO, darasheet doesn’t scale well to higher frequencies above 5kHz or so because it’s a low power opamp with very basic specifications. Can you recommend a circuit or teach me how to do this? However, the supply voltage must be regulated, or the amplitude of the two outputs will vary with the supply voltage.

Message 7 of 7. Resistor R1 and capacitor C1 form the timing components. If the source circuit is direct coupled, it must be capable of providing some current.

The resistors around the input are designed to ensure that the positive and negative integration times are identical, hence R3A and R3B in parallel because the exact half value isn’t available in most resistor series.
