Here’s a simple FET circuit that lets you switch power to ... and by taking advantage of this, you can build an amplifier, an electronic load, or a constant-current driver for some LEDs.

We have an amplifier. A simple FET radio receiver circuit showing FET biasing. The gate is biased at ground potential through the inductor, and the source is held above ground by the current in ...

One should note that the added JFET front circuit (J1A and J1B) will increase the gain bandwidth product of the amplifier by the gain of the FET circuit. For example, at 2 mA per JFET, the ...

and operational amplifiers. An introduction to continuous-time filters is also provided, as are the basic principles of sampled-data circuits, especially switched-capacitor circuits. The final chapter ...

Thermal noise current in MOSFET is given by Since noise voltages and currents are small, they can be represented as part of small signal model as shown below Noise Analysis of Common Source Amplifier ...
