Ensure +5/-5 dual supply for chip TL062 IC3. Gnd is common ps ground, let grounds radiate from ground plane in one side of PCB. R3-R8 is an attenuator that may need to be designed or modified.
In output R23 is for protection from shorting of +5V supply, R23 can also go to an unregulated or external
supply [...]
In this page, I introduce the sawtooth wave oscillator which used the operational amplifier (TL082).
The composition of this circuit is the same as the triangular wave oscillator basically and is using two operational amplifiers. At the circuit diagram above, IC(1/2) is the Schmitt circuit and IC(2/2) is the integration circuit.
The difference with the triangular wave [...]
