46 IN-CIRCUIT TRANSISTOR TESTER by A. Rigby In electronic troubleshooting a transistor is generally not above suspicion until it responds correctly to the usual diode-tests with an ohmmeter. Before ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

did you have ever tried to find connections for a transistor o mosfet with bad luck? no more with this easy project! It' s a microprocessor based (pic16f867) little system, it gives all possible ...

Abstract: A transistor amplifier with nonlinear tunnel-diode or backward-diode feedback is described for use as a resistor-coupled threshold logic circuit or general purpose switch. The tunnel-diode ...

Most of electronics deals with Tracing Curves, be it the characteristic transfer curve for a feedback loop, a resistor’s straight VI line or a transistor’s collector voltage versus current curve.

This DIY FAB Transistor Tester is a compact device designed to identify and measure various electronic components. It uses an ATmega328P-based Arduino UNO to test and display data such as pin ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

Abstract: A set of new models of varying complexity and accuracy is derived for the large-signal transient behavior of bipolar transistor and diode structures found in integrated circuits. The ...

The concept of negative resistance has always fascinated me. Of course, a true negative resistance is not possible, and what is meant is a negative differential resistance (NDR). But of course knowing ...
