as shown on its data sheet. Even with only nine transistors, the μA702 circuit is not quite the simplest possible op-amp circuit, as it contains a few of Bob Widlar’s tricks to improve performance.

includes a low-frequency resistive attenuation in the numerator (when the capacitors are open circuits) along with a zero and a pole. Generally, it is possible to determine the DC gain, poles and ...

Power-supply bypassing: Adequate power-supply bypassing can also be critical when optimizing the performance of a high-frequency circuit. Although the modern op amp has excellent power-supply ...

Op amps solve most problems in analog circuit design—if you know how to use them. Here are some resources to help expand your op-amp knowledge base. Whenever you need an amplifier or have a ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential ...
