【Abstract】 The principle of a single chip integrated temperature transducer circuit is discussed. The transducer uses the intrinsic bandgap reference current source as a sensing core of the temperature. The transducer circuit which integrated measuring temperature circuit and external circuit on a chip has been designed and simulated with PSPICE. This transducer has many peculiarities such as miniature, lower power, and higher accuracy, so that is suitable for biomedical application.更多还原
