    integrator phase not reaching 90 degrees

    Re: integrator phase Far from like, more than 10 degrees off. Addendum: Some more details about my task. I am designing an OTA based gm-C integrator for a delta-sigma ADC to operate in 300kHz to 600kHz, and I am required to have its phase to within 10% error from 90 degrees in the operating...

    integrator phase not reaching 90 degrees

    Re: integrator phase Thanks for the reply. My target application is for a delta-sigma ADC. What i know of is that if my integrator's phase is far from 90 degrees, if i input a square wave, i don't get the expected triangular wave. Surely there could be more problems? Or probably a more...

    integrator phase not reaching 90 degrees

    integrator phase Sorry if this question sounds simple. We all know that an ideal integrator has a phase of 90 degrees. Actual integrators are designed to be within a certain range from that angle. What are the problems if an integrator failed to achieve a phase close to 90 degrees? Thanks!
