A 4OGbit/s/GHz ICs realised using 0.2 mu m GaAs HEMTs. A multiplying factor as high as 64 was reached. The DC consumption is 900mW.enGaAs electronicsGaAs-ElektronikPLLpseudomorphic HEMTVCO62166738440 Gbit/s/GHz clock recovery and frequency multiplying AlGaAs/GaAs-HEMT-IC using injection-synchronised narrowband ring-VCOs and auxiliary PLLsAlGaAs/GaAs-HEMT-IC zur 40 Gbit/s/GHz Taktrückgewinnung und Frequenzvervielfachung mit einem injektionssynchronisierten schmalbandingen Ring-VCO und einer Hilfs-PLLjournal article
