ABSTRACT
The report presents the development of an exponential (anti-logarithmic) time-impulse analog-to-digital con-
verter (ADC). The converter is of the integrating type, where a reference voltage is integrated in a logarithmic
dependence until the integrated value becomes equal to the input analog voltage. The obtained time interval is
then used to enable a binary counter, which counts with a constant clock frequency. The number of counted
pulses is in an exponential dependence on the input analog voltage, and the binary representation of this number
forms the output digital code. Graphs, circuit diagrams, and analytical relations are presented.
Keywords: exponential (anti-logarithmic) analog-to-digital converter (ADC).
