Abstract :
A new IC temperature transducer is described. Main features are: easy calibration, high-output voltage (100 mV//spl deg/C), low-output impedance (70 /spl Omega/), high accuracy (/spl plusmn/0.1/spl deg/C; 20-50/spl deg/C) and low-power dissipation (250 /spl mu/W). The new device, which uses the intrinsic bandgap voltage of silicon as a reference, is especially suited to clinical use.
