In feedback systems loop gain, open loop gain, and closed loop gain are all concepts that are important to understand. The transfer function for closed loop gain is: The quantity A is known as the ...

A common problem that engineers are faced with is the need to determine the closed-loop bandwidth of their operational amplifier (op amp) circuit. Some data sheets specify unity-gain bandwidth while ...

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 ...
