Abstract :
A new technique to linearize the temperature-frequency relationship of an astable multivibrator using one thermistor is proposed. The center frequency can be adjusted at any set frequency by an adjustable resistance. Furthermore, the oscillation frequency is not affected by the change of supply voltage.
