In a p⁺n junction diode under reverse bias, the magnitude of electric field is maximum at

A P⁺-N junction has a built-in potential of 0.8 V. The depletion layer width at a reverse bias of 1.2V is 2 µm. For a reverse bias of 7.2 V, the depletion layer width will be:

The DC current gain ($$\beta$$) of a BJT is 50. Assuming that the emitter injection efficiency is 0.995, the base transport factor is:

In the CMOS inverter circuit shown, if the transconductance parameters of the NMOS and PMOS transistors are
K_n = K_p = μ_nC_OX$$\frac{W_n}{L_n}$$ = μ_pC_OX$$\frac{W_P}{L_P}$$= 40 μA/V² and their threshold voltages are V_T = 1 V, the current I is:
