Title: Temperature compensation Post by Ghitani on Apr 17th, 2008, 5:49pm Hi everybody, Can anyone suggest me ideas for temperature compensation in ring ICO i.e. making tuning C/Cs less sensetive to temperature variations? Thanks, Ghitani |

Title: Re: Temperature compensation Post by Ghitani on Apr 18th, 2008, 4:05am Thanks for your reply. Regarding architecture, I used replica bias ICO with a differential delay cell of triode load (similar to Razavi's). Is the PTAT current is the only solution? Thanks, Ghitani |
