Abstract :
A circuit which operates by normalizing the difference between two input currents by their summation, called a differential operation circuit with current inputs, is developed using a switched-capacitor circuit technique. This circuit operates with a nonlinearity of 0.1% for the summation of input currents greater than 1 mu A because of the removal of the analog divider used in the conventional circuit.<>
