Abstract: | Describes the use of multiple collector lateral bipolar transistors as precision current splitting elements suitable for use in high resolution monolithic D/A convertor design. Multiple collector structures result in better overall linearity and smaller chip area than previously suggested techniques. A six-bit convertor implemented on a linear bipolar semicustom array is used to demonstrate the advantages of this technique |
