Abstract
A high precision voltage reference circuit is disclosed which replaces two current bias sources, with a single current mirror. Curvature-error correction is established with a modified current mirror circuit. Another object of this disclosure is the addition of a MOSFET device, to alleviate the output voltage variation, due to the channel modulation effect of the origin of the voltage reference.
