Changes in the output frequency of a voltage controlled oscillator circuit due to temperature changes are compensated for by shunting a resistor with two series diode resistor combinations. The variation in the diodes' voltage drip with temperature provides a resistance that varies with temperature, to correct for other resistance or capacitive changes with temperature in the circuit, thereby obtaining a more stable oscillator frequency in a varying temperature environment. Compensating for temperature effects by shunting a resistor with a means whose resistance decreases with temperature is a method applicable to circuits other that oscillators.
