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).

Although current-feedback operational amplifiers (op amps) have been on the market since the 1990s, the current-feedback fully differential amplifier was not introduced until 2007. There are several ...

Initially introduced as the industry's fastest, the EL5367 triple current-feedback amplifier delivers a gain-of-1 bandwidth of 1 GHz while operating from a 5V to 12V supply with a total current ...

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 ...
