Bandgap voltage reference and method with further temperature correction |
摘要 |
A voltage reference circuit (26) provides a stable output reference voltage over a wide temperature range. A high temperature curvature correction circuit (36) is enabled at a first predetermined temperature to adjust the output voltage accordingly. A low temperature curvature correction circuit (38) is enabled at temperatures below a second predetermined temperature to similarly affect a output voltage. The preferred embodiment, the high and low curvature correction circuits (36, 38) are operable to vary the current through one or more resistors in a bandgap circuit (26) or other reference circuit.
