This circuit was obtained from an American documentation from the 1970s. Information on the current obtained and the winding of the transformer is not given.
An way to change the frequency of the previous oscillator (CIR112E) is to add a variable capacitor in the...
From an input signal, and using an unusual current source, this circuit generates a ramp, that is, a...
