One of the most common requests I get from engineers is for a comparison of voltage-feedback op amps and current-feedback op amps. It is impossible to determine which one better suits a given ...

Though current feedback operational amplifiers (CFOAs) are still less common in educational circles and technical literature than voltage feedback operational amplifiers (VFOAs or VFAs), they have ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Current-feedback (CFB) op amps have earned their reputation in many applications that need bandwidth, without compromising other noise and high-speed characteristics. They have served these needs ...

Designers are finding that the performance of readily available high-speed op amps offers sufficient bandwidth for video applications. And 75 ? input and output termination is simple, given the op amp ...

Analog Devices has developed an fast voltage-feedback op-amp which it claims has unprecedently low noise. The AD8099 offers a slew-rate of 1,600V/µs and a 5GHz gain-bandwidth product, while ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...
