LM10 Op Amp Application Circuits – Works with 1.1 V
The LM10 is a pioneering operational amplifier designed to operate from single ended power inputs with voltages as low as 1.1V, and up to as high as 40V. As can be witnessed in Figure 1, the device consists of an op amp, a precision 200 mV band-gap voltage reference, and a reference amplifier, all encased […]
Neon Lamps – Working and Application Circuits
A neon lamp is a glow lamp made up of a glass cover, fixed with a pair of segregated electrodes and containing an inert gas (neon or argon). The main application of a neon lamp is in the form of indicator lamps or pilot lamps. When supplied with a low voltage, the resistance between the […]
Random LED Number Generator for Gambling Application
In this post I have explained a random LED number generator circuit consisting of a 4 x 5 LED matrix, numbered from 1 to 20. On pressing a push button these LEDs begin illuminating randomly, until finally a single LED corresponding to a specific number remains illuminated. Thus, this random LED number generator can be […]
BJT Emitter-Follower – Working, Application Circuits
In this post I have explained how to use a transistor emitter follower configuration in practical electronic circuits, we study this through a few different example application circuits. An emitter follower is one of the standard transistor configurations which is also referred to as common collector transistor configuration. Let’s try to first understand what’s an […]
Tunnel Diode – Working and Application Circuit
A tunnel diode is a type of semiconductor diode which features a negative resistance on account of a quantum mechanical effect known as tunneling. In this post I have explained the basic characteristics and working of tunnel diodes, and also a simple application circuit using this device. We will see how a tunnel diode could […]
