ABSTRACT:
A computational circuit that includes a first capacitive coupling that connects a plurality of analog input voltages to a first inverter. The first inverter is connected to a second inverter through a connecting capacitance. A first feedback capacitance connects the output of the first inverter to its input, and a second feedback capacitance connects the output of the second inverter to its input. A first additional capacitance is operatively connected between ground and the first capacitive coupling, and a second additional capacitance is connected between ground and the connecting capacitance. The values of the first and second additional capacitances is selected such that the closed-loop gains of the first and second inverters are substantially equal.
