Abstract

PURPOSE:To shorten delayed times and to reduce the number of constituting elements, by constituting logical operation circuits of Y=-A.B and Y=-A+B with two transistors. CONSTITUTION:A logical operation circuit of Y=-A.B is composed of an inverter 1 and an AND circuit 2. An input terminal 3 at one end is connected to an output terminal 5 through a P channel MOSFET 4. The terminal 5 is grounded through an N channel MOSFET 6, and an input terminal at the other end is connected to each gate of FETs 6 and 4. Moreover, another logical operation circuit Y=-A+B is composed of an inverter 12 and an OR circuit 13. Therefore, the number of constituting elements can be reduced to two FETs and the number of FETs through which signals pass can also be reduced, and thus, delayed times can be reduced.
