The Sawtooth wave generator circuit composed of the CD4040 is as shown in the figure. This circuit is composed of the clock oscillator, the CD4040 10-bit counter, the R-2R ladder network, the 78L05 reference voltage generator, the A1 buffer amplifier. The clock oscillator uses the astable multivibrator which is composed of the gate circuit G1, and it can be used in the low frequency oscillation. The CD4040 is the binary counter, you can produce the high precision sawtooth wave by increasing the number of bits. If the VDD terminal voltage of the CD4040 is not stable, the amplitude of the sawtooth wave will change, so we need to use the 78L05 three-port stabilizer to stabilize the voltage.
