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, ...

Many high-speed applications require driving a circuit element that is capacitive in nature. In order to gain bandwidth, capacitive loads are often driven by a buffer; however, most high-speed buffers ...

Based on an improved internal architecture, the CFBplus OPA684 current feedback (CFB) op amp features an internally closed-loop input buffer stage that is said to boost the ICÕs performance ...
