If you rather use the MOSFET to switch on/off, saturation setting can be useful for a good efficiency. Low-level signal amplifier is usually biased in the "linear" response region; high-level amplification calls for saturation setting but one ...
Web22 mei 2024 · An AC equivalent of a swamped common source amplifier is shown in Figure 13.2.2. This is a generic prototype and is suitable for any variation on device and bias type. Ultimately, all of the amplifiers can be reduced down to this equivalent, occasionally with some resistance values left out (either opened or shorted). WebA MOSFET is a four-terminal device having source (S), gate (G), drain (D) and body (B) terminals. In general, The body of the MOSFET is in connection with the source terminal thus forming a three-terminal device such as a field-effect transistor. MOSFET is generally considered as a transistor and employed in both the analog and digital circuits.
