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 ...

bipolar junction transistor

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...

Portable thermal anemometer hot-transistor bias compensation nulls battery discharge droop

All thermal anemometers work by inferring air speed from measurements of thermal impedance (Z) between a heated sensor and the surrounding air: An example of the constant power type can be found in ...

Smart Biasing Keeps RF Power Amplifier On Track

Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...

pnp transistor

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

Zero-Bias Power-Detector Circuits based on MoS

Scientists from RWTH Aachen University, AMO GmbH, AIXTRON SE, and EPFL have demonstrated power detectors based on Molybdenum disulphide (MoS 2) that operate at zero bias.

Test Setup Checks Transistors’ hFEs When Tight Control Is Important

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...
