In the circuit shown, \(R_1 = 100 \, \text{k}\Omega\) and \(R_2 = 1 \, \text{k}\Omega\). If the base-to-emitter voltage of the npn BJT is 0.7 V and the collector-to-emitter voltage is 5.2 V, the \(\beta\) (current gain) of the BJT is _________ (round off to two decimal places).
In the small signal circuit shown, the enhancement mode n-channel MOSFET is biased in saturation with transconductance \( g_m \). If channel length modulation is ignored, the small signal impedance looking into the node P is given by _________
In the small signal circuit shown, the enhancement mode n-channel MOSFET is biased in saturation with a transconductance \( g_m \). A small signal low-frequency voltage \( v_d \) injected at the supply terminal results in a small signal voltage fluctuation \( v_o \) at the output. If the channel length modulation of the MOSFET is ignored, the small signal gain \( \frac{v_o}{v_d} \) is given by _________
