Challenge Problems
Push your limits with advanced challenges
Design a low-noise amplifier with a noise figure preferably below 5dB. Given R_s = 50Ω, calculate R_n needed.
💡 Hint: Use the NF equation in designing the circuit with proper resistance values.
Create a Gm-C filter with a desired bandwidth of 1MHz. If the capacitor C is 1nF, determine the required transconductance g_m.
