| Abstract: | An IC technique for clock recovery and frequency multiplication was developed by combining a preprocessor, an injection-synchronised narrowband ring voltage controlled oscillator, and a phaselocked loop. A 40 Gbit/s/GHz IC was realised using 0.2 μm GaAs HEMTs. A multiplying factor as high as 64 was reached. The DC consumption is 900 mW |
