The operating conditions and assumptions of the following dynamic logic circuits are as follows:
- Power supply = 1.8V
- ViL = 0.6V on inverter
- ViH = 1.1V
- Leakage current = 10nA
- Minimum operating clock frequency = 10kHz
If you have obtained the following output waveform, find the parasitic capacitance value that appears in X node.
