For the inverter below (reportedly from Australia), assume the input signal is a 100MHz, independent, random binary signal with a probability,

P(A=1)=0.7. For the pMOS transistor, assume μₚCₒₓ (W/L)=300μA/V², Vₜₚ =−0.4 V, and λ=0.
Estimate the dynamic power dissipated by this inverter only for charging and discharging the output capacitor.

Final answer:

To estimate the dynamic power dissipated by the inverter for charging and discharging the output capacitor, we need to calculate the charging and discharging energies. However, since the capacitance value is not provided in the question, we cannot calculate the exact dynamic power dissipated by the inverter.

Step-by-step explanation:

To estimate the dynamic power dissipated by the inverter for charging and discharging the output capacitor, we need to calculate the charging and discharging energies. The dynamic power can be calculated using the equation: Pdissipated = (Echarge + Edischarge) × f, where Echarge is the charging energy, Edischarge is the discharging energy, and f is the operating frequency.

Echarge = ½ × C × V², where C is the output capacitance and V is the voltage swing. Edischarge is equal to Echarge. Therefore, we can substitute Echarge for Edischarge.

Now, to find the dynamic power, we need to know the capacitance value. Unfortunately, the capacitance value is not provided in the question, so it is not possible to calculate the exact dynamic power dissipated by the inverter.
