    PSoC 3: opamp (follower mode) stability with 100 MFD load

    senthilnathan.lingasamy

      Will the opamp in PSoC 3 be stable in follower mode with upto 100 microfarad of load capacitance?

         

      Ans:

         

      With a 100MFD load, the opamp (in voltage follower mode) will be stable.

         

      But it will have reduced bandwidth and hence, reduced slew rate. Phase margin is also very low leading to a longer settling time.
