A SECOND ORDER TEMPERATURE COMPENSATED BAND GAP VOLTAGE REFERENCE |
摘要 |
A voltage reference circuit design which is temperature compensated to the second order is presented. The circuit comprises a sub-circuit for generating a bandgap voltage reference temperature compensated to the first order and a sub-circuit having a differential amplifier for generating a current having a second order temperature dependency. The current in turn is used for generating a correction voltage having a second order temperature dependency. The first order band gap voltage reference and the correction voltage are combined to provide the second order temperature compensated band gap voltage reference. |
