The current-feedback OTA (CFB OTA) recently appeared in a new classification of operational amplifiers. It is dual to the operational floating amplifier (OFA), so all OFA circuits can readily be transposed into CFB OTA circuits. This paper discusses the theoretical basis of the CFB OTA, shows its relation to the OFA, and compares their performance in a simple V–I converter by showing how both c...

Current Feedback Amplifiers (CFA) are discussed in this report. Current Feedback Amplifiers employ the current mode of signal processing to achieve higher gain-bandwidth product and greater slew rates than those of a Voltage Feedback Amplifier (VFA). The Current Feedback Amplifier topology has an inherent advantage over that of the the Voltage Feedback Amplifier, wherein the amplifier gain can ...
