  • Temperature compensating circuit
    Patent number: 5537049
    Abstract: A thermistor network for a low temperature component of a temperature compensating circuit includes a series resistor-capacitor combination in parallel with a thermistor and a capacitor. The presence of the capacitor in series with the resistor permits DC measurement of the resistance of the resistor without the measurement being affected by current flow through the thermistor. This low temperature component may be connected in series with a high temperature component of the temperature compensating circuit. Alternatively, the low temperature component can be connected in parallel with the high temperature component.
