3.5Gsps MIPI C-PHY Receiver Circuit for Automatic Test Equipment

This paper presents a 3.5Gsps MIPI C-PHY analog front-end receiver circuit for Automatic Test Equipment. This circuit has two features. First, it is made entirely of off-the-shelf components. Second, it has powerful CTLE to compensate for transmission line loss. Since it does not use ASIC, it is possible to add functions at a low cost and in a short time. In the wafer test environment, the loss between the wafer and the receiving circuit is large. This CTLE can be fine-tuned and effectively compensate for the transmission line loss of the developed equipment.
