Editor’s note: My good friend and long-time colleague, Michael Steffes, expands upon my introduction article, Rauch filter basics, and adds some very useful and practical insights into the Rauch ...

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 ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

The stability of high-unity-gain-bandwidth op amps is susceptible to stray capacitances. Instability doesn't first show up as oscillation, but rather pronounced overshoot and ringing. Op amps such as ...

A very common application is to use a low-noise, moderate-gain first stage in a sensor path, followed by a fully differential amplifier (FDA), to provide added gain and centering on the common-mode ...
