The work examines the electrical circuit of a voltage reference generator for the pipeline analog-to-digital converter (ADC). This circuit possess high accuracy of reference levels formation, good temperature stability and it is low-sensitive to supply voltage deviations. The main feature of the circuit is that it uses two independent resistive dividers in the form of matrices and specialized buffers to decrease reference voltage distortions on load. This paper gives simulation results of the voltage reference generator on load. We obtained dependences of reference voltages on temperature and supply voltage and took measurements of prototype models.
