An ideal MOS capacitor (p-type semiconductor) is shown in the figure. The MOS capacitor is under strong inversion with V_G = 2V. The corresponding inversion charge density (Q_IN) is 2.2 $$\mu$$C/cm². Assume oxide capacitance per unit area as C_ox = 1.7 $$\mu$$F/cm². For V_G = 4V, the value of Q_IN is __________ $$\mu$$C/cm² (rounded off to one decimal place).

Consider the circuit shown in the figure. Assume base-to-emitter voltage V_BE=0.8 V and common base current gain $$\left(\alpha\right)$$ of the transistor is unity. The value of the collector-to–emitter voltage V_CE (in volt) is _______.

An npn bipolar junction transistor (BJT) is operating in the active region. If the reverse bias across the base-collector junction is increased, then
