Abstract
A high-speed monolithic dual operational amplifier using the 'current feedback' approach is described which enables errors inherent in this type of amplifier to cancel in many applications. The advantages of this approach include a closed-loop bandwidth relatively independent of gain and a very high slew-rate capability. The disadvantages include considerably reduced DC performance compared to a conventional operational amplifier. Techniques for improving the DC performance of the individual amplifiers are described.<>
