Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>Two new CMOS analog continuous‐time equalizers for high‐speed short‐haul optical fiber communications are presented in this paper. The proposed structures compensate the limited bandwidth‐length product of 1‐mm step‐index polymer optical fiber channels (45 MHz, 100 m) and have been designed in a standard 0.18‐µm CMOS process. The equalizers are aimed for multi‐gigabit short‐range applications, targeting up to 2 Gb/s through a 50‐m step‐index polymer optical fiber. The prototypes operate with a single supply voltage of only 1 V and overcome the severe limitations suffered by the widely used degenerated differential pair caused by the low supply voltage.
