<p>A voltage controlled oscillator (VCO) having high temperature stability and wide voltage/frequency linearity comprises a multivibrator switched by bipolar transistor switching means (Q9, Q10). Temperature fluctuations of the bipolar transistor switching means are compensated by a FET current source (T11, T12) coupled thereto. To provide a linear relationship of frequency vs. voltage over wide voltage range, the bipolar transistor switching means is further regulated by a plurality of resistor and diode networks (R4, Q1, Q2; R5, Q3, Q4).</p> |
