摘要

本文介绍了用于数字温度补偿晶体振荡器(DTCXO)的温度传感器和模数转换器(ADC)。电路在标准的0.6 um CMOS工艺中实现，具有双聚层和三金属层。传感器和ADC的组合在3.3 k /s下从3.3 v电源输出1.14 mW，总面积仅为1 mm/sup 2/。

The CMOS temperature sensor and cyclic ADC for low power single chip DTCXO

This paper describes a temperature sensor and an ADC (analog-to-digital converter) for use in the DTCXO (Digitally Temperature Compensated Crystal Oscillator). The circuits were implemented in a standard 0.6 um CMOS process with two-poly and three-metal layers. The combination of the sensor and ADC draws 1.14 mW at 3.3 kS/s from a 3.3-V supply and total area is only 1 mm/sup 2/.
