This 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 can share 50‐Ω terminations and common‐mode capacitors while maintaining a perfectly matched load balance. The proposed dual mode receiver supports up to 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 lane in the C‐PHY.
