Abstract
A temperature compensating circuit designed in two parts, a temperature-pulse width conversion circuit (X) and a temperature compensating circuit (Y.sub.N) permit the sharing of the temperature-pulse width conversion circuit by a plurality of temperature compensating circuits. Each temperature conversion circuit is relatively uncomplicated in construction, utilizing only resistors and a switch means. The temperature-pulse width conversion circuit utilizes a temperature sensitive element, like a thermistor, in a circuit with an operational amplifier. The output of the operational amplifier is supplied to a pulse width converter for generating the pulse width signal that carries the temperature compensation factor to be used in temperatures compensating the signal received by the temperature compensating circuit.
