Design of Temperature Compensation Circuit to Compensate Temperature Characteristics of VCO [PDF]
The Journal of Korean Institute of Electromagnetic Engineering and Science, 2010 In this paper, temperature compensation circuit for the X-band voltage controlled oscillator(VCO) is presented by using the temperature sensor with the OP-AMP circuit. The frequency drifting by the temperature could be compensated by applying the tuning voltage which include the linearly changing output voltage of the temperature sensor.
