Abstract
A clock-controlled voltage-to-frequency converter in which the output frequency is proportional to the square root of the input voltage is described and a detailed error analysis is presented. Accuracies of about 0.02% of full-scale for the voltage input range from 1 mV to 10 V have been achieved using commercially-available CMOS components in good agreement with theoretical expectations
