| 摘要 |
A circuit is disclosed for temperature compensating the output voltage thereof with respect to undesireable temperature induced signals from a pressure transducer and/or the circuit itself. The circuit comprises a pressure transducer, two operational amplifier stages, and an output stage. One operational amplifier is coupled between the pressure transducer and a summing node. Two compensation networks, one each coupled between the pressure transducer excitation input terminals and two voltage source terminals, nulls temperature induced voltages at the summing node.
