Abstract
An IC technique for clock recovery and frequency multiplication was develop ed by combining a preprocessor, an injection-synchronised narrowband ring v oltage controlled oscillator, and a phaselocked loop. A 40Gbits/GHz IC was realised using 0.2 mu m GaAs HEMTs. A multiplying factor as high as 64 was reached. The DC consumption is 900mW.
