Abstract :
The 4:1-multiplexer reported here is based on a 21 GHz fT 0.4 μm silicon bipolar technology and operates up to 12 Gb/s. For facilitating system applications, the input signals are aligned in phase and retiming of the output signal is provided. A phase control circuit permits the choice of the optimum clock phase for the first and the second multiplexer stages; an internal delay line is not necessary. The 4:1-multiplexer consumes about 1.8 W with a single supply voltage of -4.5 V
