Pulse Generator (Oscillator) With Adjustable On-Off Period Using CA3130 Op-Amp

One of the interesting features of CA3130 op-amp  is its high input resistance, because using such high  input resistance, we can build an astable multivibrator with high R/C ratios. The figure below shows the circuit’s schematic diagram, you can see the variable resistors to adjust the “on” and “off” periods independently. Resistors R1and R2 are …
