Investigation of a method of converting voltage into code

Formulas have been obtained for the instrumental and nonlinearity errors of units in a VCC with compensating integration, and its advantages over a VCC with series counting have been determined.
It has been shown that the nonlinearity error of a VCC with compensating integration is cancelled completely for t2=t1, and will be less than the nonlinearity error of a series counting VCC for t2>t1/2.
Principles have been established for the optimal selection of the value of Uref depending on the distribution law of the input signal.
It has been shown that the errors in determining the time intervals and integrator elements affect the accuracy in a VCC with compensating integration considerably less than the corresponding errors in a series counting VCC. This makes a VCC with compensating integration the one with greatest prospects in the construction of a converter to work under difficult climatic conditions.
