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.
Sine wave generator circuit 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.
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.
The sine wave purity could be enhanced through placing adjustable resistor 25 ohms in the emitter lead of q1 x.
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 sine wave generator circuit that we will build with a transistor and resistors and capacitors is shown below.
The breadboard circuit of the circuit above is shown below.
Figure 7 shows the xr 2206 connected as a sine wave generator.
Sine wave generator circuit built with a transistor.
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.
