Abstract
In the design of an integrated circuit for comparing serial data signals, the number of transistor elements can be reduced by implementing the comparison gate (12) based on the associated truth table rather than by using a general comparison gate component. Using this method, an exclusive OR gate (22) can be implemented using two transistor elements (221, 222), an exclusive NOR gate (52) can be implemented using two transistor elements (521, 522), an AND gate (62) can be implemented using a single transistor element (621), and an OR gate (72) can be implemented using a single transistor element (721). The reduced number of elements used to implement the comparison gates can provide a transistor element saving in the associated circuit.
