Abstract

An asynchronous sensing differential logic circuit using a charge-recycling technique includes a control block carrying out a logical operation on a request signal from a preceding stage and a request signal for a succeeding stage, and outputting a first or second input enable signal and a first or second clock signal, a functional block carrying out an operation on an input data according to the first or second input enable signals and the first or second clock signals from the control block, and outputting a first or second output enable signal and an output data, and a latch block triggered by an acknowledge signal from the succeeding stage, and outputting a request signal for the succeeding stage and a final output data by carrying out an operation on the first or second output enable signals and the output data from the functional block.
