See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications in a world where electronics are becoming more pervasive. Finding materials ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of current and enable signal processing in everything from small devices to ...

Mark Levinson has announced it is now shipping the No320S Preamplifier. A direct descendant of the critically acclaimed No32 Reference Preamplifier, the No320S features audio circuits, controls, ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.
