I want to implement a Current operational Amplifier(COA), I have difficulty in finding the applications where COA are used. I want some references that can explain the applications of COA in detail and not just in one line.
I think it's the same as an Operational Transconductance Amplifier (OTA),
I think the OTA is a controlled current source with a high input resistance (with other words: A voltage-to-current converter).
