Abstract :
Current feedback (CFB) operational amplifiers offer significant advantages and disadvantages in use. Many of the advantages and disadvantages are fundamental to the amplifier architecture. Specific topics addressed include slew rate, the absence of gain-bandwidth product, sources of error, open loop gain, cost and user ability
