Abstract (en)
[origin: EP1102148A1] The circuit has a component sensitive to low temperature changes in order to control the amplifier final output voltage. The constant voltage generator comprises a reference voltage generator (110) and an amplifier (126) connected between this reference voltage generator and the output terminal. A voltage divider (130) is connected to one input of the amplifier to provide a feedback voltage. The voltage divider comprises at least a first resistance (132) in series with an element (150) whose resistance varies as a function of the prevailing low temperature. The temperature dependence of this resistance value is different from that of the first resistance (132) and thus this provides a feedback which is smaller in the lower part of the temperature range.
