Dependence of a Thermoresistive Sensor-Based Constant Temperature Measurement Instrument Response on DC Amplifier Input Offset Voltage
In this paper is analyzed the dependence of the temporal response of a thermoresistive sensor-based, feedback constant temperature circuit on the input offset voltage of the operational amplifier employed in the circuit. Experimental results of the performance evaluation of a proposed feedback automatic input offset control circuit are presented
