Discussion Overview
The discussion revolves around the calculation and understanding of a cascode amplifier, including specific voltage values referenced from a textbook. Participants seek clarification on the circuit schematic and associated components.
Discussion Character
- Technical explanation, Conceptual clarification, Homework-related
Main Points Raised
- One participant requests help with calculating a cascode amplifier and asks for formulas related to it.
- Another participant suggests placing the ground symbol at the bottom of the schematic for clarity regarding bias voltages and questions the input and output connections in the circuit.
- A further contribution mentions the typical use of a decoupling capacitor on the base of Q1 in a cascode amplifier and inquires if this is depicted in the referenced book.
- A link to a schematic of a cascode amplifier is provided for reference.
- A participant expresses gratitude for the assistance and indicates that they have corrected their earlier miscalculations.
Areas of Agreement / Disagreement
The discussion includes multiple viewpoints and suggestions regarding the schematic and calculations, with no clear consensus reached on the specific calculations or configurations.
Contextual Notes
Participants reference specific voltage values and circuit configurations without fully resolving the assumptions or calculations involved.

I fixed your thread title to "cascode" amplifier, which I think is what you are asking about, right?
You should put the ground symbol at the bottom of your schematic so your bias voltages make more sense. And are you meaning to put the AC input signal into the base of Q2 and take the output at the collector of Q1?

Also, for a cascode amplifier, you would typically use a decoupling capacitor on the base of Q1. Is anything like that shown in your book?
