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 ...

Bipolar Transistor Circuit Design & Analysis, Part 4

In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...

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.

Setup Bypasses The Problems Of Boot-Strap/Bias-Supply Circuits

In some power-supply applications, the pulse-width-modulator (PWM) controller is powered up from an auxiliary winding tapped off the power stages transformer (Fig. 1). This technique reduces power ...

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 ...
