Re: overshoot problem

Some of the known ways are following...

1. Taking rise time / fall time into account.

2. Size of the switch which leads to the node caps

3. differential scheme, not to avoid the nature, but to cancell out

4. Also, some times after layout the paracitics of the nodes help to improve this one
