Can capacitors and inductors be used in amplifiers? How about considering and describing the noise of these two components? 1

In amplifiers, capacitors and inductors are commonly used components that play important roles in circuits. However, these two components also generate noise in the amplifier, which has a certain impact on the performance of ATTINY13A-SSU amplifier. Below, we will separately introduce the noise issues of capacitors and inductors in amplifiers. diode

Capacitors, as a component for storing charges, are commonly used in the coupling and filtering circuits of amplifiers. In the coupling circuit of an amplifier, capacitors are used to isolate the input signal from the DC bias voltage of the amplifier, ensuring that the amplifier operates at the appropriate operating point. In filtering circuits, capacitors are used to attenuate or remove high-frequency noise or spurious signals from the amplifier output signal, in order to obtain a clean output signal.diode

Inductors, as components that store magnetic field energy, are commonly used in the coupling and filtering circuits of amplifiers. In a coupled circuit, inductors are used to isolate the input signal from the DC bias voltage of the amplifier, ensuring that the amplifier operates at the appropriate operating point. In filtering circuits, inductors are used to attenuate or remove low-frequency noise or spurious signals from the amplifier output signal, in order to obtain a clean output signal.diode
