It is somewhat similar to the circuit proposed in [9]: it employs a voltage comparator to monitor the difference between a temperature-independent reference voltage, [V.sub.REF], and a voltage with a complementary-to-absolute-temperature variation, [V.sub.NTC], generated by a bipolar transistor.
The amplifier in turn is connected to the voltage regulator LM385-1.5 and the voltage comparator LM393N.
The shaper circuit is realized with the voltage comparator I1 of type LM 339 whereas the monostable circuits are made in the circuits [I.sub.2] and [I.sub.3] of 74LS121 type.
The amplified output from the op-amp is connected to one input of the voltage comparator; the other input of the comparator is connected to a reference voltage.
