A merged compressor flip-flop circuit is provided. The circuit includes a compressor circuit having a front-end and a back-end, the front-end configured to receive four input bits and to output a first carry-bit to a back-end of a second compressor circuit, the front end further configured to output intermediate sum signals to the back-end of the compressor circuit, the back-end configured to receive the intermediate sum signals from the front-end and further configured to receive a second carry-bit from a front-end of a third compressor circuit, the back-end further configured to output a sum-bit and a third carry-bit based upon the intermediate sum signals and the second carry-bit, and a flip-flop circuit configure to receive the sum-bit and third carry-bit and to store the sum-bit and third carry-bit, wherein the back-end of the compressor circuit directly drives the sum-bit and third carry-bit into the flip-flop circuit
