With the decrease of transistor feature sizes into the ultra-deep submicron range, leakage power becomes an important design challenge for circuit designers. This paper examines the application of anasynchronous design paradigm named Multi-Threshold NULL Convention Logic MTNCL to adaptive beamforming circuits. MTNCL and synchronous designs were implemented using the IBM 130nm bulk CMOS process for power and area comparison. The MTNCL design showed substantial improvements in terms of active energy and leakage power compared to the equivalent synchronous design.
