The triangle wave and square wave circuit composed of the analog switch is as shown in the figure. In this circuit, the resistance values of the adjustment potentiometer RP2 and RP3 change the reference voltage UR1 and UR2, so we can change the triangular wave voltage level and amplitude accurately and independently. You can change the resistance value of potentiometer RP1 to change the oscillation frequency of the circuit. The UR1 and UR2 can use the external power supply, if it is used with the D/A converter, they can form the digital wave amplitude control triangulation oscillator. If we assume that the stable voltage of VD3 and VD4 is Uz, the oscillation period T=2(RRP1+R1)C1(UR2-UR1)/Uz+0.7), the 0.7(V) is the positive voltage drop of VD3 or VD4.
