A capacitor placed across terminals of these devices induces pole splitting and can be split into two capacitors to ground in the Miller effect. The ubiquitous “741” type of one of these devices (10[3])uses internal frequency compensation to avoid (-5[1])instability (-5[1])while using series-shunt feedback. The common-mode rejection ratio quantifies how well these devices perform with differential input. They’re not diodes, but these devices (10[1])are represented by a triangle on a circuit (-5[1])diagram. Infinite input impedance and zero input voltage between the non-inverting and inverting terminal are rules used to solve circuits with the “operational” or “op” type (10[1])of these (10[1])devices (10[2])with very high (10[1])open-loop (10[1])gain. For 10 points, name these devices that increase the strength of a signal, such as one coming from an electric guitar. ■END■ (10[1])
