Double domino driver
The double domino driver is fully differential and is optimized for low switching noise and power. The noise behavior and power dissipation is improved by limiting the signal swing. The domino driver consists of a combination of mini drivers, each of which is switched on in two steps. In the first step a voltage equal to a fraction of the supply voltage propagates through the chain of mini drivers and turn them partially on. In the second step the voltage is increased to its maximum value and is made to propagate through the chain, turning the mini drivers completely on. The rise and fall time of the output signal can be increased by adding mini drivers. For a 5 volt supply voltage with 5 mini drivers the switching noise in decreased to levels less than 100 micro volts. The power dissipation with this driver is least as compared to ECL and other logic systems. The double domino driver is useful in communication and VLSI systems.
