Abstract :
A new monolithic current-controlled oscillator, which features a highly linear frequency range of more than seven decades, has been realized in a compatible JFET-bipolar technology. Low current performance is accomplished by the use of two p-channel JFET-source-followers and a special load consisting of a string of diodes driven by a continuous current source. Temperature compensation for frequency and output voltage is easily achievable by means of a PTAT current source.
