The most popular and stable biasing method. It uses a resistive divider network to make the Q-point independent of transistor Module 3: Field-Effect Transistors (FETs)

: Push-pull configuration, higher efficiency (up to 78.5%), prone to crossover distortion.

Possesses a physical channel that can be enhanced or depleted by varying the gate voltage.

of the input cycle. High linearity but very poor maximum efficiency (typically around 25% to 50%).

: Uses a separate DC voltage source to bias the gate terminal.

As semesters passed, Mira’s hair silvered. The university asked her to write a comprehensive set of lecture slides — a full PowerPoint that could introduce students to electronic devices and circuit theory from diodes to dynamic systems. She thought of the city at night, of circuits everywhere, and decided the slides should be a storybook: clear, visual, and human.
