In Figure 5, the NMOS inputs are VA = VB = 5 V, the threshold voltage is Vtn = 2.8 V, and the initial output voltage is VO = 0 V. Provide an estimate for the output voltage. In Figure 5, the PMOS inputs are VA = VB = 0 V, the threshold voltage is Vtp = 3.2 V, and the initial output voltage is VO = 5 V. Provide an estimate for the output voltage.
