A 30-gb/s 70-mW one-stage 4:1 multiplexer in 0.13- mu m CMOS
A completely integrated 4:1 multiplexer for high-speed operation and low power consumption is presented. The circuit uses a new architecture where four data streams are multiplexed in one stage. Pulses with a duty cycle of 25% switch the inputs to the multiplexer (MUX) output. The pulses are generat...

| description | A completely integrated 4:1 multiplexer for high-speed operation and low power consumption is presented. The circuit uses a new architecture where four data streams are multiplexed in one stage. Pulses with a duty cycle of 25% switch the inputs to the multiplexer (MUX) output. The pulses are generated from the clock signal and the divided clock signal. Measurement results show the performance of the IQ divider. Current-mode logic is used because of the higher speed compared to static CMOS and the robustness against common-mode disturbances. The multiplexer uses no output buffer and directly drives the 50- Omega environment. The lower number of gates compared to the conventional tree topology enables low-power design. Relaxed timing conditions are additional benefits of the one-stage MUX topology. The IC is fabricated in a 0.13- mu m standard bulk CMOS technology and uses 1.5-V supply voltage. The MUX works up to 30 Gb/s and consumes 70 mW. |
