Sine Wave Generator Circuit Using Transistor

The sine wave generator circuit that we will build with a transistor and resistors and capacitors is shown below.

Sine wave generator circuit using transistor.

The post explains a very simple 3 phase sine wave generator circuit using only three bipolar transistors and a few passive components for initiating the desired three phase output. The tone frequency is defined through capacitor c1 and one of the 10 k wirewound pots r1 to rn. The breadboard circuit of the circuit above is shown below. So first for the power requirements of this circuit we use 4 5v to the 555 timer chip.

If you need a sine wave generator that can be set to any frequency in the 0 01 hz to 1 mhz or more take a look at the xr 2206. The xr 2206 is an older ic that is still available and a great way to generate sine square and triangle waves over a wide frequency range. The sine wave purity could be enhanced through placing adjustable resistor 25 ohms in the emitter lead of q1 x. However the pwm from ic sg3524 is being blocked by the collectors of the bc547 transistors at the bases of the power stage transistors.

Sine wave is most commonly known as waveform for alternating current in this circuit we will also build that alternating waveform we can adjust the frequency or reduce the noise of the sine. First and foremost we use 9vdc of power for this circuit. Hello sir i actually built the above inverter circuit using ic sg3524 and 555 timer as the sine wave generator. Previously we have built simple square wave generator circuit today in this tutorial we are going to show you how to generate sine wave using few basic components like transistor resistor and capacitor.

Sine wave generator circuit built with a transistor. The breadboard schematic of the above circuit is shown below. The circuit again is based on a simple relaxation oscillator concept using a type 2n2646 unijunction transistor to generate the audio note and commute a loudspeaker. The two most widely used types of transistor waveform generator circuits are the oscillator types that produce sine waves and use transistors as linear amplifying elements and the multivibrator types that generate square or rectangular waveforms and use transistors as digital switching elements.

I feed the 555 timer stage with 5v beside 8v fed to the ic sg3524. How it works referring to the 3 phase sine wave generator circuit we can see three identical transistor stages configured in a cross coupled manner having.
