Small Signal Analysis

A small signal source, Vi(t) = A cos(10^5t) + B sin(10^7t) is applied to a BJT circuit as shown in the Figure. Assume zero source resistance, VBE = 0.7 V, βdc = 99, Early voltage =...

In the circuit below, assume that the long channel NMOS transistor is biased in saturation. The small signal trans-conductance of the transistor is $g_m$. Neglect body effect, chan...

In the circuit shown below, the transistors M₁ and M₂ are biased in saturation. Their small signal transconductances are g_m1 and g_m2 respectively. Neglect body effect, channel le...
