3D Receiver for Molecular Communications in Internet of Organoids

Organoids have garnered attention due to their effectiveness in modeling the 3D structure of organ interactions. However, the communication engineering perspective has received relatively little attention. One way to achieve organoids communication is molecular communication (MC). MC is a bio-inspired communication paradigm that uses molecules as information carriers. It is considered one of the most promising methods for enabling the Internet of Nano-Things (IoNT) and nanonetworks. BioFETs are commonly used to implement practical MC receivers. However, most previous analysis have focused on a planar device, neglecting considerations like the threshold voltage, inter-symbol interference (ISI) and its potential 3D structure. This paper introduces the first FinFET-based MC receiver that covers both the top and side gates with receptors. Both binding noise and flicker noise are considered in the analysis. The performance, in terms of signal-to-noise ratio (SNR) and symbol error probability (SEP), is compared with that of the 2D receiver.
