-===== Op-Amp Measurements =====
-==== Bandwidth ====
-Measuring the bandwidth of an operational amplifier (op-amp) means determining the frequency range over which it can amplify signals accurately. Bandwidth is typically defined as the frequency at which the gain drops by 3 dB compared to its low-frequency value. There are two closely related bandwidth concepts:
-  * **Small-signal (linear) bandwidth**: The frequency at which the gain drops by 3 dB (to 0.707 of its mid-band value).
-  * **Gain-Bandwidth Product (GBW)**: For most voltage-feedback op-amps, the product of closed-loop gain and bandwidth is approximately constant.
-<code>
-Bandwidth = GBW / Closed-loop gain
-</code>
