description: The given work is devoted to the study of influence of the gain error of the ADC stage on its main characteristics. The aim of the work is to de- velop amplifying elements with reduced power consumption and compare their characteristics (gain, unity gain bandwidth and power consumption) in order to determine the most suitable for use in a 2.5-bit pipeline ADC stage. The simulation was carried out in Matlab / Simulink and Cadence Virtuoso. As a result of the work, the structure of the pipelined ADC was de- scribed in detail, as well as the structure of the 1.5-bit and 2.5-bit stages that make up the ADC. The analysis of the structure of a 2.5-bit ADC is carried out taking into account the imperfection (finiteness) of the amplifi- cation factor of the op-amp. The results of modeling a 12-bit pipelined ADC based on 2.5-bit stages are presented, the effect of the op-amp gain error on the main characteristics of the ADC is estimated. The development of three amplifying elements with reduced power consumption was carried out, as well as a comparison of the characteristics of the amplifying. Vari- ants of the distribution of amplifying elements over the ADC stages are proposed, and the expected power consumption is calculated. The results of the work can be used to build a pipelined ADC based on 2.5-bit stages with reduced power consumption. Variants of the distribution of amplifying elements have been pro- posed to reduce the power consumption of the ADC.
