Cascode C-S Amplifier (Find Poles in Frequency Response)

AI Thread Summary
The discussion revolves around determining the poles in the frequency response of a cascode common-source amplifier, specifically at nodes A, X, and Y. The problem emphasizes the importance of the Miller Effect when analyzing node X and suggests calculating the DC gain of node X relative to node A. Participants express uncertainty about how to begin solving the problem, indicating a need for guidance on foundational equations and concepts, particularly the Miller Effect. The conversation highlights a common expectation for effort before receiving assistance in academic forums. Understanding the relationships between the nodes and applying relevant equations is crucial for progressing in the solution.

Homework Statement


Heres the question, I honestly don't know where to even begin :(

An AC model of a cascode common-source amplifier is shown below. M1 and M2 are biased in saturation mode. The parasitic capacitors in the transistors are included. Determine the poles in frequency response at node A, X, and Y respectively.

(Hint: When calculating node X, Miller Effect should be included. You need to figure out the DC gain of node X versus node A.)

well, I've noticed most people here won't give a lot of help unless you make some sort of effort. i googled miller effect and found an equation for it. You may want to start by writing equations like that and other relevant equations.
