Hello
I want to know for continuous time filters mostly OTA-C filters are used but why not OTRA (Operational transresistance amplifier) ? especially for low frequency applications(biomedical) OTRA are not used why?Is there some complexity issue? similarly op-amps are also not preferred.
Can some one help me in this matter.
