Features of Complex Functional Block Designing of 14 Bit Digital to Analog Converter of Submicron Integrated Circuit of «Oncrystalsystem» Type
Abstract
This article considers main causes of technological scattering influence on digital-to analog converter characteristics (DAC) while designing according to CMOS technology with design engineering rate- 0,18(mcm). An improved scheme of inclusion of current generator matrix of high-order digits while increasing number of digits of digit-to-analog converters from 10 to 14 is offered. A program for checking mixing circuitry effectiveness according to one of DAC key characteristic performance - integral nonlinearity (INL) is developed. A combination for including matrix with the least index of INL matrix of high-order digits is presented.
