COMBINATIONAL LOGIC STRUCTURE USING PASS TRANSISTORS

摘要

COMBINATIONAL LOGIC STRUCTURE USING PASS TRANSISTORS Sterling Whitaker PASS transistors are used to reduce the layout complexity of logic circuits by using PASS transistors connected to pass a first and second input function to an output node in response to selected CONTROL signals, thereby to generate a selected output function on the output node. The PASS transistor comprises a transistor capable of passing an input function in response to a CONTROL signal applied to the transistor thereby to generate an output function related to the input function. In general, the input function comprises less than all of a set of input variables and the CONTROL function comprises one or more of the remainder of the set of input variables.
