A current-feedback amplifier is a well-known component with many uses. Its basic block diagram shows that its input stage is a voltage follower—in practice, a symmetrical emitter follower (Figure 1).

Current feedback amplifiers are one of the oldest amplifier topologies around. I remember the days when Comlinear ruled the market in the 80s with their high speed offerings. Analog Devices, ...

The OPA695 low-power, current-feedback amplifier carries impressive bandwidth credentials at low and high gains. Developed by Texas Instruments' Burr-Brown division, it's well suited for video signal ...

Voltage-Feedback operational amplifiers (VFA op amps) allow circuit designers to swap gain for bandwidth. current-feedback op amps (CFAs) are simpler to use than VFAs, but do not offer gain-bandwidth ...

Marantz today announced the $500 PM5005 entry-level integrated amplifier, which is the first in its class to offer current feedback architecture – a feature that normally is reserved for the more ...
