Hi
A am working on a 12 bit 2.4 GSample/sec. DAC using HBT 0.3u process.
I have completed all stages except one.
I need a c-mos to ECL converter which is driven by a c-mos encoder (composed of some nor gates) and will drive a Bipolar diffrential switch (possible input resistance 2-5 Mohms)
The key word here is high speed. I think I have tried enough topologies I had found anywhere and I think I need something new.
I am open for any ideas.
Note: The process used is a very high standard one. You can discard general mismatch problems while thinking.
