Basic Behavioural and Device Modelsodels. In the initial phase of the design, it is important to validate the intended functionality of the overall circuit at the level of mathematics, without regard for the implementation details. Therefore, the knowledge of functionality of fundamental devices, namely, a switch, voltage, and curren

Multistage Interface hierarchically; during its development stage, systems are often split into more than ten levels of hierarchy. Once the hierarchy chain is established and each of the stages is replaced by its equivalent Thévenin or Norton model, each of the blocks is considered to be a “black box” described by its

Basic Semiconductor Devicesminal. That is to say, large waveform at the output terminal is faithful replica of the small input side waveform, thus the amplification. Key point, however, is that the device merely . the output current flow. The signal energy used both at the input and output sides is provided by the . energy so

Introduction to Frequency Analysis of Amplifiersudes all frequencies, from minus infinity to plus infinity. Nonetheless, we already know that elements capable to store energy need a finite amount of time to change their internal states. For slow changes this time delay is negligible, thus “low frequency” approximation produces acceptable results.

Electrical Noise“hum” in an audio signal are typical electrical noise manifestations. Noise mainly affects receiving systems, where it sets the minimum signal level that it is possible to recover before it becomes swamped by the noise. We note that amplifying a signal already mixed with noise does not help the sign

Electrical Resonancepotential forms. In the absence of friction (i.e. energy dissipation), a pendulum would oscillate forever. Similarly, after two ideal electrical elements capable of storing energy (a capacitor and an inductor) are connected in parallel then the total initial energy of the system bounces back and for
