While you may be stuck with regulator noise floor in a system, that doesn't mean that your circuit's performance has to suffer. One of the transistorized circuits described here may make a marginally ...

A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...

In the past, an aspiring electronics enthusiast would have started with simple transistor circuits such as a light sensitive switch, a simple electric organ, or an AM radio such as the one ...

Lesson 4 Using Transistors: Let’s Get Transistorized! Overview In this lesson, students build two circuits and explore how transistors function. Objectives • To observe how a transistor functions in a ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types ...

Hitherto, transistors have been unsuitable for amplifying these potentials direct because their intrinsic noise at low frequencies was too high and because the input impedance of the simpler ...

By adding a transistor and differential amp to your thermocouple interface, you can non-intrusively detect these common fault modes in the sensor or its leads; the circuit can ...

Simple Electronics was part of the imprint’s Learnabout series, and it took the basic premise of its predecessor away from the realm of radio into other transistor circuits.

One secret to creating the world's fastest silicon-based flexible transistors: a very, very tiny knife. Engineers have now pioneered a unique method that could allow manufacturers to easily and ...
