Abstract
AbstractThis paper presents a 14‐Gb/s dual‐mode receiver with MIPI D‐PHY and C‐PHY interfaces for mobile display drivers. To reduce size overhead from the dual‐mode interfaces, we propose the termination circuit that shares 50‐Ω terminations and common‐mode capacitors while maintaining a perfectly matched load balance. The proposed dual‐mode receiver can support 14‐Gb/s total bandwidth in each interface mode, resulting in broad compatibility with application processors. A mobile display driver using the proposed dual‐mode receiver is fabricated in a 28‐nm high‐voltage CMOS process and verified up to 3.5 Gb/s per lane in the D‐PHY mode and 2.2 Gs/s per trio in the C‐PHY.
