Op amp attenuation
WebAs will be seen, the op amp is most prone to instability when it is configured as a unity-gain follower, either because (a) there is no attenuation in the loop, or (b) large common-mode swings, though not substantially affecting accuracy of the signal gain, can modulate the loop gain into unstable regions.

Amplifier open-loop Bode plot The frequency operation of the standard operational amplifier (op amp) product can have multiple poles and zeros in the transfer function from sub-hertz to the zero-dB cut-off …
WebMDPI electronics 2024년 7월 26일. This brief presents a hybrid of voltage- and current-mode line drivers for the turbo controller area network (CAN). The current-mode scheme prevents signal attenuation caused by source termination resistors, and it enhances signal power efficiency. On top of that, an adaptive amplitude tuning is implemented ... WebThe inverting attenuator below uses a "T" pad to accomplish attenuation and avoid the instability issue completely. The calculator only uses two values of resistor: R1 and R2. If you remove R1, the circuit reverts to an inverting gain stage, with Rg = R2A + R2B, and Rf = R2C + R2D. Since all R2's are the same value, the gain of the circuit is -1.
