Abstract :
Resonant tunneling diodes (RTDs) have demonstrated promising circuit characteristics of high speed switching property and versatile functionality with negative differential resistance (NDR). In this paper, we propose novel programmable logic elements (PLEs) that can be configured to realize all three- or four-input logic functions. These simple RTD-based circuit elements are implemented with threshold gates (TGs) and multi-threshold threshold gates (MTTGs) by employing programmable monostable-bistable logic element (MOBILE) principles. We also developed a dynamically reconfigurable scheme based on our PLE structures which facilitate nanopipelining without incurring delay overheads.
