    High speed decoding and decision ICs for 4-level ETDM fibre optic transmission systems are presented. The circuits were fabricated in a InP/lnGaAs HBT technology with Ft = 53 GHz and Fmax = 40 GHz. A 4-level decoding circuit using a mux core architecture and a binary decision circuit were designed and measured. The potential performance of the decoder were experimentally assessed up to 16 GBaud (32 Gbit/s) (input data). The decision circuit is a D MSFF which was tested up to 22 Gbit/s
