A silicon crystal is doped with 1.5x10$^{15}$ cm$^{-3}$ of P atoms. Intrinsic concentration is n$_i$=1.5x10$^{10}$ cm$^{-3}$. Calculate the Fermi energy E$_F$ of this crystal, relative to the conduction band energy in the intrinsic Si at room temperature. Assume that the effective mass of electrons in this Si is 10 times smaller than that of the holes and the energy gap is 1.1 eV.

f) The gain of a negative feedback amplifier system, $A_f$ can be written as: $\frac{A_{OL}}{1+\beta \times A_{OL}}$ Define $A_{OL}$ and $\beta$. Explain how an amplifier gain is stabilised by feedback, with reference to this equation. g) The triangular element in the circuit shown in Figure Q1g represents an ideal current amplifier with a gain of 100. Work out the value of the voltage gain if $R_g = 3 \text{ k}\Omega$ and $R_L = 9 \text{ k}\Omega$.
