Temperature-Compensated Current Source Using a Bandgap Reference
Original Publication Date: 1989-Sep-01
Included in the Prior Art Database: 2005-Jan-29
The subject disclosure provides a temperature-compensated voltage reference in a module that contains a digital-to-analog converter (DAC). The DAC output voltage tolerance, which is primarily a function of the tolerance and tracking of its current sources, must be minimized to reduce step-to-step adjustment tolerance.
