A feedback amplifier providing very wide bandwidth which is substantially independent of amplifier gain over a substantial range of frequencies within a given bandwidth. The amplifier employs a pair of operational amplifier stages (OA1, OA2) connected in tandem in a circuit utilizing current feedback. The inverting inputs of the two stages are tied together at a common point (V1), thereby developing the current feedback to render the gain and bandwidth of the circuit independently variable. |
