Abstract
A bipolar monolithic IC temperature transducer with an operating temperature range of -125/spl deg/C to +200/spl deg/C has been designed, fabricated, and tested. The two-terminal device, which is fabricated using laser trimmed thin-film-on-silicon technology, is a calibrated temperature dependent current source with an average output impedence of 10 M/spl Omega/ over the 3.5-V to 30-V range of input voltage. Overall absolute accuracies of /spl plusmn/0.5/spl deg/C from -75/spl deg/C to +150/spl deg/C have been achieved on a scale of 1 /spl mu/A/K under optimum operating conditions.
