A multi-rate low-voltage continuous-time adaptive equalizer is presented in this paper. It was designed to compensate the high-frequency attenuation of a 50-m 1-mm core step-index plastic optical fiber (SI-POF) for input data ranges from 400 Mbps up to 1.25 Gbps. The equalization is based on the power-spectrum technique and the circuit operates with a single supply voltage of 1 V. The structure is formed by two loops which do not interact with each other; one loop adapts to changes in the channel length and the other in the data rates.
