Abstract

A circuit gives each of the input signals at its inputs to a common circuit previously charged to a supply voltage through transfer transistors. When the logical condition is satisfied the common circuit remains charged; otherwise the charge changes. This is detected by a discriminator circuit and the result is indicated at the circuit output. The circuit may be of AND-, OR-, NAND- and NOR design.
