Translate An opAmp integrator to a OTA-C one

  1. Sep 20, 2010 #1
    I have a fliter that uses OpAmp based integrator. I want to make the same filter but using OTA-C instead of opamps. But I'm confused on the process of doing that. Anyone can help me on how to get the same behavior from the transition from one to an other?In other words translating the RC values in the omAmp version into the OTA version with the same behaviour

    OTA-C integrator

    The ota will be a simple differential pair with resistors as loads.

    Welcome to the PF!

    What's an OTA? What is the context of the question? (School project, personal project, etc.)

    This may be part of a university project..


    OTA: I mean operational trans-impedance amplifier.
