How to design a Triangle Wave Generator (electronic circuit)?

You can easily design the Triangle Wave Generator circuit by practicing the exercises given below. Here you can design and simulate your own electronic circuits with this Online Circuit Designer and Simulator.


Circuit Description:

This circuit is an oscillator that generates a triangle wave.

The second half of the circuit is an inverting integrator. The first op-amp starts with its two inputs in an unknown state; let's say it starts with + slightly higher than – (which is at ground). The op-amp greatly amplifies this difference, bringing its output to the op-amp's positive power supply voltage, its maximum output (15 V in this case). With this positive input, the integrator's output falls at a constant rate.

The 10k and 4k resistors act as a voltage divider which put the first op-amp's + input 4/14ths of the way from the second op-amp's output to the first op-amp's output. When this input reaches ground, then the first op-amp's output switches polarity, and the integrator switches direction, forming the other half of the triangle. When the first op-amp switches polarity again, a new cycle begins. -- Credits: Mr. Paul Falstad.
