Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

Create a Gm-C filter with a desired bandwidth of 1MHz. If the capacitor C is 1nF, determine the required transconductance g_m.

💡 Hint: Reorganize the f_c formula to solve for g_m efficiently.
