Abstract
In this work, temperature sensor and control circuit for measuring temperature are proposed. The proposed circuit can be fabricated without additional CMOS fabrication process and the output of proposed circuit is digital value. The supply voltage is 5volts and the circuit is designed by using 0.5${\mu}m$ CMOS process. The circuit for measuring temperature consists of PWM control circuit, VCO, counter and register. consisted The frequency of PWM control circuit is 23kHz and the frequency of VCO is 416kHz, 1MHz and 2MHz, respectively. The circuit operation is analyzed by using SPICE.
