ABSTRACT:
A compression type A/D converter for producing an output in the form of a digital value almost equal to the square root of the input analog value. For this purpose, the A/D converter is constructed as a dual-slope A/D converter in which the current signal for inverse integration increases as a function of a polynominal of order n (n=1) of the inverse integration period.
