It is very important that the design aspects of the NB-IoT device protocol stack ensure low module cost and low energy consumption. This is required to match the industry expected module costs. This paper outlines some of the NB-IoT Protocol stack specification flexibilities and generic design aspects that are to be considered to meet the above requirements, especially with reference to LTE.
MIPI C-PHY is suitable for mobile camera and display applications. In this paper, we proposed an effective active C-PHY driver scheme without any increase of the size and control pins. Additionally, C-PHY has many characteristics in-common with D-PHY because many parts of C-PHY were adapted from D-PHY. Therefore, we present a combo-type architecture of MIPI D-PHY and C-PHY.
