A degenerate Ga As MESFET timing decision circuit for 2.5 Gb / s optical fiber communication was designed. The SPICE simulation showed that the recovered clock frequency reached 2.5 GHz and the decision circuit transmission rate reached 2.5 Gb / s. The clock signal is sampled and the decision circuit produces the correct digital signal at a transmission rate of 2.5 Gb / s
