Low Complexity QCA‐Based 1:2n Demux Architecture With Effective Modular Design

Journal of Engineering, Volume 2026, Issue 1, 2026.
Quantum‐dot cellular automata (QCA) is a revolutionary technology operating at the nanoscale and having the ability to supplant the CMOS technology. Demultiplexers (DeMuxs) are essential combinational blocks in receiver‐side communication systems, where they perform signal distribution and serial‐to‐parallel data routing.

Simulation and Analysis of Different Configurations of Demultiplexer Chips for Digital Electronics and Communications

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
Current digital communication systems need systems with high throughput, low latency, and hardware‐efficient structures that can scale with the growing complexity of data. Multiplexing and demultiplexing methods are crucial for meeting these requirements as they allow more than one data stream to be transmitted using the same channel.
