Abstract—The presented work deals an ultra high-speed CMOS 4-2 compressor which is an essential part in fast digital arithmetic integrated circuits. Current-mode techniques have been used to improve the overall performance of the compressor. New fully differential proposed circuit improves delay to less than 37% also reduces occupied area in comparison to other high-speed conventional compressor circuits. To evaluate the performance of the proposed circuit, conventional gate level structure has been chosen and all of the circuits have been simulated in 65-nm IBM CMOS process with 1.2V power supply voltage.
Index Terms—Digital logic, 4-2 compressor, CMOS, high speed, current-mode.
