Switched bleed currents
A method, system, and apparatus for multiplexing comprising feeding a signal into a sampler, splitting a first signal into an even branch at a first set of times, splitting a second signal into an odd branch at a second set of times, feeding a switch bleed current into the first branch at the second set of time and feeding the switch bleed current into the second branch at the first set of time.
1. A method for multiplexing comprising:
feeding a signal into a sampler;
splitting a first signal into a first branch at a first set of times;
splitting a second signal into a second branch at a second set of times;
feeding a switch bleed current into the first branch at the second set of times; and
feeding the switch bleed current into the second branch at the first set of times.
2. The method of claim 1 wherein the sampler is part of a high speed low power analog to digital converter.
3. The method of claim 1 further comprising:
splitting a third signal into a third branch at a third set of times; and
feeding the switch bleed current into the third branch at the second set of times.
4. The method of claim 3 further comprising:
feeding a switch bleed current into the third branch at the first set of times;
feeding the switch bleed current into the first branch at the third set of times; and
feeding the switch bleed current into the second branch at the third set of times.
