i used a two stage cherryhooper amplifer as a limiting amplifier. But it only works when i give small singal(<30mv) in tran simulation.
The total gain is 30db. i use jazz 0.35bicoms,frequency 10gb. i met convergence promblem if i give a large input.
i think it shoule achive limiting state with large input. Could someone help me?
i think these spec can be achieved with given process.
just make sure that all mos transistors in sat region and i think gain would not be a problem but challenge is a b/w.
so far what specs you achieved???
actually i could get b/w and gain in one stage,also i could get a 30db 10gb with 2 stage,but i find it's hard to get a flat amplitude response. so the eyedigram is so bad.
have you met this question?
actually my requirements were less than what you require here so not a problem but because of BJTs used i think may be that's why it is source of noise.
or if you can send me the technology files then i can try woth this architecture and get back to you....
