Biasing That Transistor Part 4: Don’t Forget The FET

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Transistor Circuits Design

Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A ...

To bias or not bias: New audio output transistors make that decision easy

ThermalTrak integrates power output transistors with thermal bias diode. One of the major design concerns in the output section of a typical class AB audio amplifier is output bias and stability over ...

THD-Enhanced Bias Circuit Design Targets Class AB Buffers

Bias circuits for class AB buffers don't have to ruin your total harmonic distortion spec. Here's some tips on how to prevent the bias circuit from influencing the amplified signal spectrum. Bias ...

Lesson 4

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

Use Current-Mirror Biasing To Avoid Squegging In RF Oscillators

If you've ever designed an RF oscillator, you've probably encountered squegging. Sometimes called "motor boating," squegging causes oscillators to start and stop at frequencies much lower than the ...
