BAGHERIZADEH, Mehdi; MOAIYERI, Mohammad Hossein  and  ESHGHI, Mohammad. Digital counter cell design using carbon nanotube FETs. J. appl. res. technol [online]. 2017, vol.15, n.3, pp.211-222. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2016.12.005.

Compressor and counter cells are the basic blocks used to accumulate the partial products in a multiplication process. In this paper, novel high speed and low power carbon nanotube counter cells are suggested. The efficiency of circuits is improved by using carbon nanotube field-effect transistors (CNFETs). The proposed designs are 4-to-3, 5-to-3, 6-to-3, and 7-to-3 counters. Using HSPICE, these proposed designs are simulated at different conditions. Simulation results confirm that the proposed designs are the fastest counters with lowest PDP in different working circumstance.

Keywords : Compressor; Counter cell; Carbon nanotube transistor; Multiplier.
