You designed a common collector amplifier with a Vdd of 10V, R_E of 1kΩ, and a target I_C of 2mA. Determine the required base-emitter voltage for proper operation.
💡 Hint: Convert I_C to I_E using the available transistor parameters.
In a common drain amplifier, if g_m is found to be 1mA/V and r_o equals 50kΩ while R is 10kΩ, find A_v.
💡 Hint: Remember to consider the appropriate r_i value for your context.
