Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a cascode amplifier with \(g_{m1} = 2 \, mS\) and \(g_{m2} = 3 \, mS\), \(r_{o1} = 100 \, kΩ\), and \(r_{o2} = 200 \, kΩ\). Calculate the overall voltage gain.

💡 Hint: Break it down step-by-step using the provided gain formula.

Challenge 2 Hard

Design a cascode amplifier to achieve a voltage gain of 50. Given that \(g_{m1}\) is 1 mS, find the required \(g_{m2}\) and output resistances.

💡 Hint: Work with the variables in the gain equation to solve for the unknowns.
