Abstract :
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 mm2
