- Problem Statement
- What is frequency of oscillator in below circuit?
- Relevant Equations
- f = 1/(2*3.14*R*C)
I'm not sure how will this oscillator work. Assume A is low, so B will be high and the capacitor will charge through B-C- 2Mohm.
Now even D has gone high, so A will be high and B will be low and C will discharge. I'm not sure how the voltage divider rule across RC will take into effect.
I found a similar structure in this link (3rd circuit diagram):
Simple square wave generator you can build using logic gates NAND, NOT , schmitt trigger inverter IC. easy to build square wave oscialltor circuit diagrams
How will the C charge and discharge here?
