Abstract
In order to reduce the power consumption of the temperature sensor,a simple on-chip temperature-fre⁃quency converter circuit is proposed. The converter can detect temperature in terms of the proportional to absolute temperature(PTAT)current,and then converts the temperature equivalent to the frequency by using the source cou⁃pled multi-vibrator circuit. The proposed circuit has been designed and fabricated in a standard 180 nm CMOS tech⁃nology and occupies area of about 0.061 mm2. Through many practical measurement. The test results show that when the power supply voltage is 0.8 V+10%,the temperature sensor can work within the temperature range of-43℃~+85℃,and after a single point after correction,the maximum temperature error is less than ± 1℃.When the power supply voltage is 0.8 V,the average power loss at+85℃is only 500 nW.关键词
