摘要

在标准CMOS工艺中实现的温度-频率转换器只需要低成本的批量校准。它的输出频率是由工艺无关(但温度相关)的大块硅的热扩散率决定的。转换器的不准确性小于±0.5℃(3sigma)在扩展的工业温度范围从-40到105℃

A CMOS Temperature-to-Frequency Converter with an Inaccuracy of 0.5/spl deg/C (3 /spl sigma/) from -40 to 105/spl deg/C

A temperature-to-frequency converter implemented in a standard CMOS process only requires a low-cost batch calibration. Its output frequency is determined by the process-independent (but temperature-dependent) thermal diffusivity of bulk silicon. The converter's inaccuracy is less than plusmn0.5degC (3sigma) over the extended industrial temperature range from -40 to 105degC
