2. Using an op-amp

Figure 2-1 Frequency characteristics of an op-amp
Figure 2-1 Frequency characteristics of an op-amp

An op-amp has a high gain as shown in Figure 2-1. The gain is dependent on frequency. The gain also varies from device to device and is affected by temperature and other environmental conditions. Therefore, op-amps are generally used with negative feedback. Depending on conditions, negative feedback turns into positive feedback, causing the feedback loop to oscillate abnormally.
Section 2 describes feedback oscillation, basic amplifier circuits using an op-amp, a virtual short-circuit required when considering an amplifier circuit.
