Ring Oscillator Based CMOS Temperature Sensor Design
This paper presents the ring oscillator based temperature sensor. The method is highly area efficient, simple and easy for IC implementation as compared to traditional temperature sensors. The proposed temperature sensor was fabricated using 0.35 μm technology, which occupies extremely small silicon area. It exploits the frequency of the ring oscillator that is proportional to temperature, whic...
متن کاملLow power, temperature and process compensated CMOS ring oscillator
The modern communication technologies require the use of CMOS monolithic oscillators because of their small manufacturing costs and high integration capabilities. The disadvantages of CMOS ring oscillators can be compensated through the use of a VCO architecture. The control voltage of this VCO should compensate for the frequency drift due to process and temperature.
