How (Not) to Decouple High-Speed Operational Amplifiers
When a capacitor is used for decoupling, it is connected as a shunt element to carry RF energy from a specific point in a circuit, away from a circuit power pin, and to ground. Ideally, the …
Feedback Resistor and Capacitor in amplifier
Positive feedback increases the gain of the amplifier, and an old (early 20th century) radio design employed positive feedback for just that purpose. The problem with …
Why does this op-amp circuit require a resistor to ground?
If the signal source is coupled in with a capacitor, and if your op amp cannot work with an input that is floating with regard to DC, then Rin might be needed. Be aware that the …
