Nano-magnet based ultra-low power logic design using non-majority gates

In this paper we explore the intriguing possibility of nano-magnet based logic using non-majority gates. The design approach can offer significant area, delay and energy advantages, compared to a majority-gate based logic design. Our analysis based on NAND-gate based ring-oscillator (RO) shows an improvement of 29% in frequency and 33% in area compared to MQCA based design. Moreover, using the performance metric of millions of operations per second per micro-watt power (P) per micron square area (A) - MOPS/P/A, our RO design with narrow gap cladding H_CLOCK enhancement, shows an improvement of 13X compared to an RO in 15 nm CMOS technology.
