All of us must have encountered this problem many times in our lives (atleast once!); you know what I am talking about? Dropping our mobile phones, smart phones, tablets, camcorders, digital cameras, pen drives! In this era of gadgets we depend on a lot of portable devices to make our life more entertaining – we […]
This article is not something related to our usual electronics technology, rather we are dealing a little with web technologies and Internet marketing stuff. I know many of you electronics geeks and enthusiasts may not be well aware of technologies behind websites and techniques used to bring loads of traffic to a website. I will

Hi all Readers, We always try to publish useful circuits and topics for our readers. After publishing an article we usually measure how well it was received among our readers. We have two options for measuring success of an article published; first being the number of page views it has got and the second being
Introduction In the earlier 60’s it was discrete logic used by electronic industry. The digital system would look like noodle like maze of wiring between components. Once it is built it will be difficult to do rework on it. Sometimes the designers would forget what they have designed for! Manufacturing such systems was very difficult

RC Phase shift oscillator. RC phase shift oscillator or simply RC oscillator is a type of oscillator where a simple RC network (resistor-capacitor) network is used for giving the required phase shift to the feedback signal. In LC oscillators like Hartley oscillator and Colpitts oscillator an LC network (inductor- capacitor network) is used for providing
What is a FET Phase Shift Oscillator? A phase shift oscillator is a circuit that produces sign waves. The output is fed back to the input which changes the ‘phase’ of the waves. The phase shift increases with frequency and can reach a maximum of 180 degrees. Phase shift oscillators have a wide range of
An introduction to Audio Oscillators also known as RC Oscillators So far, we have considered the oscillators which use L-C tuned circuit that causes a phase shift of 180° due to inductive or capacitive coupling in addition to a 180° phase shift produced by the transistor itself. The oscillators employing L-C elements, called the L-C
In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically viÂbrating crystal. The crystal (usually quartz) has a high degree of stability in holding conÂstant at whatever frequency the crystal is originally cut to operate. The crystal oscillators are, therefore, used whenever great stability is needed, for example, in communication transÂmitters, and
Hartley oscillator circuit. Hartley oscillator was invented in 1915 by the american engineer Ralph Hartley while he was working for the Western Electric company. The original design was tube based and he got a patent for it in the year 1920. In a Hartley oscillator  the oscillation frequency is determined by a tank circuit comprising
The Clapp oscillator shown in figure. is a refinement of the Colpitt’s oscillator. The single inductor found in the Colpitt’s oscillator is replaced by a series L-C combination. Addition of capacitor Ca in series with L improves the frequency stability and eliminates the effect of transistor parameters on the operation of the circuit. The

Colpitts Oscillator An oscillator is used to produce electronic signal with oscillating periods. Eg: Sine wave, square wave etc.. Oscillators are broadly classified into two – linear oscillators and non-linear oscillators. As the name implies, linear oscillators are used to produce linear or sinusiodal waveforms. Whereas, non-linear oscillators are used to produce non-linear (non-sinusoidal output
Tuned base oscillator. Tune base oscillator is another type of transistor based LC oscillator where the tuned circuit (tank circuit) Â is placed between the base and ground of the transistor. The tuned base oscillator is also called “Armstrong oscillator” after the name of its inventor. The tuned circuit essentially consists of a transformer and capacitor
Tuned collector oscillator. Tuned collector oscillation is a type of transistor LC oscillator where the tuned circuit (tank) consists of a  transformer and a capacitor is connected in the collector circuit of the transistor. Tuned collector oscillator is of course the simplest and the basic type of LC oscillators. The tuned circuit connected at the
