Ambipolar independent double gate FET logic

In this work, we present a review of recent logic circuit design research using ambipolar independent double gate field effect transistors (Am-ICDGFETs). In a first approach, we examine compact logic and show that, with respect to conventional CMOS-like static logic structures and for comparable power consumption, time delay and integration density can be reduced by 25% and 45% respectively. We then turn to reconfigurability, and demonstrate a key use of ambipolarity in a 16-function dynamically reconfigurable logic cell based on a sum-of-products Boolean function implementation, which achieves remarkable gains in terms of power consumption (9x) and in terms of intrinsic time delay (5x) with respect to conventional 16nm LP CMOS-based look-up table circuits. Finally, we tackle the question of logic synthesis for design paradigms using such fine-grain reconfigurable cells, and show how binary decision diagrams can be adapted to this purpose to generate, in a flexible way, multiple input selective function sets. Using this technique, a generated circuit was also evaluated and shown to compare very favorably to its CMOS equivalent.
