Abstract :
A 1:4-demultiplexer IC meeting the essential requirements for lightwave communication systems has been designed based on a 21 GHz f T 0.4 μm Si bipolar process. The circuit provides features such as bit-rotation control, clock enable control, outputs aligned in time, and phase aligner for clock signals. It operates up to 14 Gb/s (14 GHz) with a phase margin of ⩾250°. The power consumption is 2 W with a -4.5 V supply. 1:16-demultiplexer operation is demonstrated on the basis of 1:4-demultiplexer IC´s at 10 Gb/s
