  1. Closed: Resistor value variation on TSMC 0.18um Technology Process and PRA

    Hello to everyone,

    currently I'm designing an active RC filter, it is a CR-RC2 Pulse Shaper. The technology process is TSMC 180nm (Link:...
  2. Closed: Re: Rail to rail input-output fully differential Op-Amp with class AB buffer driver

    Hi Junus,

    it seems that you have a problem with the Class AB bias generator. If you plot Vod vs Vid, there is little range for Vid (centered at 0) where Vod = 0, generating crossover distortion....
  3. Closed: Re: Rail to rail input-output fully differential Op-Amp with class AB buffer driver

    Hi Junus,

    it seems that the problem is related to the CM output voltage which is not well defined. Since the output of the first stage is very high impedance, little changes in the current would...

    Hi,

    you could check this book:...
  5. Closed: Re: fully differential amplifier based on folded cascode topology with class AB buffe

    The CMFB works this way. Rcm1's sense output common-mode voltage which it is attached to the source of M51 and M52. The gates of M51 and M52 are at the same and constant voltage, generated by the...
  6. Closed: Re: Rail to rail input-output fully differential Op-Amp with class AB buffer driver

    Hi Junus,

    can you show simulations of what isn't working? As frankrose said above, it would be useful to give DC annotations, in order to check whether the transistors are operating in the active...
