Auxiliary design tool for square wave generator

Square wave is a common application waveform in circuit , Common square wave generator circuits are as follows ：

Although the above square wave circuit looks very simple , But if we build the real object according to the above circuit , It often fails to vibrate , At the same time, I don't know how to debug .

In order to facilitate the construction of physical objects , Little detours , We have sorted out a square wave circuit aided design form for you . You just need to fill in the corresponding data in the form , The overall circuit parameter calculation can be completed .

potential .

The table uses the following ：

First step ： Fill in the parameters in the white box in the table

The second step ： Build simulation circuit , Set the circuit parameters to the parameters in the white block diagram ; Then a square wave can be generated ;

The above operational amplifier power supply mode is dual power supply . The circuit parameter setting is simple , But the negative power supply will give many people a headache . In practical circuit application , Generating a negative voltage also increases the cost of the circuit . So it's not enough to learn dual power supply , We must also learn the design method of oscillation circuit of single power supply .

The following figure shows the single power supply mode ：

Again , For single power supply mode , We also made the corresponding auxiliary design form ：

We just need to fill in the corresponding parameters , Then fill the parameters into the circuit , The square wave circuit can be set Work plan ：
