Basic MOSFET Amplifier

https://www.electronics-tutorials.ws/amplifier/mosfet-amplifier.html The universal voltage divider biasing circuit is a popular biasing technique used to establish a desired DC operating condition of bipolar transistor amplifiers as well as mosfet amplifiers. The advantage of the voltage divider biasing network is that the MOSFET, or indeed a bipolar transistor, can be biased from a single DC supply. But first we need to know where to bias the gate for our mosfet amplifier.
