Logic circuit for use in microprocessor for executing NAND operation, has parallel arranged unidirectional circuit arrangements to block current flow from input of circuit to control input of switching unit

摘要

The circuit has parallel arranged unidirectional circuit arrangements (15) to block a current flow from an input of the circuit to a control input of a switching unit (20). A switching unit (17) has a control input to supply a clock signal, which determines whether the unit (17) is opened or closed. A common connection of the arrangement and parasitic capacitance are connected with a voltage potential, when the unit (17) is closed. An independent claim is also included for a microprocessor with a clock generator and logic circuits to execute an NAND-operation.
