A sine wave generator is actually a sine wave oscillator circuit which generates an exponentially rising and falling sinusoidal waveform. The 9 simple sine wave generator circuits presented in the following article are easy to build, since they incorporate a small number of ordinary electronic components, and can be used for generating an exponentially varying […]

High Frequency PWM Electric Arc Metal Engraver Circuit
Today I am showing you how to make very powerful pen style electric arc metal engraver circuit using IC 555 and MOSFET. Actually this idea is inspired by one of my blog reader, and my friend Mr. August. He made one crude engraver using 6V transformer and tractor charging coil, but he wanted a smooth […]
Build this Simple Zener-Stabilized Wien Bridge Sine Wave Generator Circuit
This zener diode stabilized Wien Bridge sine wave oscillator circuit is very easy to build and test, let me explain full working in simple way. Basically here we are using TL072 opamp which needs dual supply like +15V on pin 8 and -15V on pin 4. Pin 1 is our main output pin from where […]
Phase Shift Oscillator Circuits – Wien-Bridge, Buffered, Quadrature, Bubba
A phase-shift oscillator is an oscillator circuit designed to generate a sinewave output. It operates with a single active element such as a BJT or an op amp configured in an inverting amplifier mode. The circuit arrangement creates a feedback from the output to the input through using an RC (resistor/capacitor) circuit arranged in a […]
Understanding CMOS IC 4035 Datasheet – 4-Bit Parallel In Parallel Out Shift Register
So now we are talking about this digital IC called 4035 which is made using CMOS technology, that means it will use very low current and will give us high noise immunity. Inside this IC we have got 4 flip-flops which are arranged in such a way that they can hold and shift 4-bit data. […]
IC 4047 Astable, Monostable Oscillator Circuits
In an IC 4047 astable oscillator circuit, the output of the IC continuously generates a switching ON/OFF signal. Since the output is never in a stable state and constantly switches between and low and high, it is called an astable multivibrator. The astable ON/OFF switching frequency is adjustable and can be varied by changing the […]
