Abstract

PURPOSE:To obtain a simple temp. sensor with high accuracy which is not influenced by a temp. change of thermocouples such as resistance and secular change by detecting pinch-off voltage making the border where drain electric current depending on the MOSFET temp. does not flow. CONSTITUTION:In an MOSFET G such as a depletion type, drain voltage VD and source resistance R2 are set so that drain electric current ID becomes infinitesimal and voltage VGS between gate sources which becomes the pinch-off voltage depending on temp. is detected as voltage at both sides of the resistance R2. The voltage VGS and reference voltage are treated at a differential and operating amplifier 1 and temp. is detected. In the case, an additional guantity of the current I in accordance with the temp. rise of FETGG does not almost influence to the voltage VGS and a temp. detection is exactly performed. Further, the voltage VGS is not affected by resistance of the connected measuring circuit and the temp. characteristics of the amplifier and secular change. By such a way, a simple temp. sensor with high accuracy which is not influenced by a temp. change of thermocouples such as resistance and secular change is obtained.
