  • Thermometer
    Patent number: 5228781
    Abstract: The thermometer consists of an operational amplifier ratio bridge which is made up of at least one arm having a 3-terminal high impedance temperature sensor one of whose leads being connected to the output of an operational amplifier whose gain has been stabilized and whose output impedance has been rendered negligible by negative feedback. The other lead being connected to the input of an operational amplifier whose gain has been stabilized and whose input impedance has been rendered negligible by negative feedback. Standard arms, comprising standard resistors and capacitors and operational amplifiers whose gain has been stabilized by negative feedback may be connected in parallel with the first arm.
