Semiconductor Electronics Material Devices and Simple Circuits

150922 Consider a p-n junction as a capacitor, formed with \(p\) and \(n\)-materials acting as thin metal electrodes and depletion layer width acting as separation between them, Biasing on this, assume that a \(\mathbf{n - p}-\mathrm{n}\) transistor is working as an amplifier in \(C E\) configuration. If \(C_1\) and \(C_2\) are the base-emitter and collector-emitter junction capacitances, then

2 \(\mathrm{C}_1 \lt \mathrm{C}_2\)
3 \(\mathrm{C}_1=\mathrm{C}_2\)
4 \(\mathrm{C}_1=\mathrm{C}_2=0\)
