For a single-ended input – single-ended output differential amplifier using silicon transistors, we calculate the differential gain and output voltage step by step. Given: * Input voltage: (v_{in} = 10,\text{mV} = 0.01,\text{V}) * Collector resistors: (R_{C1} = R_{C2} = 47,\text{k}\Omega = 47000,\Omega) * Emitter resistor: (R_E = 39,\text{k}\Omega = 39000,\Omega) * Supply voltage: (\pm 12,\text{V}) * Si transistors ((V_T = 26,\text{mV}) at room temperature) Step 1: Calculate transconductance (g_m) For a differential pair, the transconductance is:
