| 摘要 |
<p>The invention provides a power supply circuit for applying a temperature-compensating supply voltage across a temperature-sensitive transducer (such as a strain gauge transducer), the circuit comprising a first operational amplifier, means for applying an output level determining voltage to one (preferably the negative) input of the amplifier, means for applying a temperature-dependent output slope determining voltage to the other (preferably the positive) input of the amplifier, and means for applying the resultant temperature-dependent output voltage of the amplifier to the transducer.</p> |
