Abstract
A single 400 series thermistor is interfaced to a patient monitor designed to accept only dual thermistor probes by a circuit including first and second cascaded negative impedance converters connected to first and second discrete resistors. The first and second discrete resistors are operative to alter the slope of and shift the resistance versus temperature characteristic of the circuit, while the negative impedance converters scale the characteristic.
