Hello
I want to know if I design a OTA(operational transconductance maplifier) let suppose of 70dBgain but when usig the OTA in designing a filter the close loop gain of the filter is 0dB ideally practically -6dB as shown in the attached figure. Then what is the reason behind to get such high gain when the filter designed using that OTA is 0dB.
