A new interconnect method for radio frequency intra‐chip communications using transistors‐based distributed access

Abstract

This paper presents a new radio frequency channel access method to a radio frequency (RF) interconnect for intra‐chip communications. The method overcomes the undesired effects that come from multiple connections in classical methods. It is based on an active access, through transistors associated in a distributed topology. This leads to better properties in terms of reflection and transmission coefficients along the transmission line. This approach is validated by making a deep comparison with the basic existing access methods (eg, direct and capacitive). Measurements on a test circuit using the 0.25 μm SiGe BiCMOS technology confirm the good performance of the proposed access.

Framework for Design Exploration and Performance Analysis of RF-NoC Manycore Architecture

“…Moreover, design and sizing of RF elements for RF-NoC architectures based on waveguides have already been proposed in the literature, demonstrating the feasibility of the approach. The interested reader could find more details in [6][7][8].…”

An improved hybrid network‐on‐chip with flexible topology and frugal routing

“…The waveguide provides a communication channel that is well-known during the design phase. Most importantly, the design and size of RF elements for such NoC architectures have been widely discussed in the literature [16][17][18][19], proving the approach's viability.…”

Optimization of spectral resources allocations using the PAPR criterion in the context of a MPSoC based on RF interconnections

“…To allow communications between all clusters simultaneously and in both directions, it takes 992 channels. We propose to use OFDMA that makes reconfigurability easier without changing the architecture of the RF transceivers [1][7] [12]. Taking into account the 992 transmissions and the band {20-40} GHz imposed by the technology in the WiNoCoD project (BiC-MOS 0.25μm technology), we propose a system of 1024 sub-carriers and a width of 19.531 MHz/subcarrier.…”
