**Educational Content on Small Signal Model for Amplifiers** **Problem Statement:** 2) Draw the small signal model for the amplifier shown below. Do not make any approximations. Label Vin and Vo. **Diagram Explanation:** The schematic diagram illustrates a multi-stage amplifier circuit. It consists of two transistor stages, each with associated resistors and capacitors. **Components and Connections:** - **Stage 1:** - The input signal, labeled as Vin, is fed into the gate of the first transistor. - **Resistors:** - R1 connects Vin to the gate of the transistor. - R2 connects the gate to Vdd. - R3 connects the source of the transistor to the ground. - The output from the first stage is labeled as Vo1. - **Coupling:** - A coupling capacitor, labeled C, connects the output from stage 1 (Vo1) to the input of stage 2. This capacitor blocks DC while allowing AC signals to pass through. - **Stage 2:** - The input to the second stage, labeled as Vin2, is connected to the gate of the second transistor. - **Resistors:** - R4 connects Vin2 to Vdd. - R5 connects the source of this transistor to the ground. - R6 is connected to the drain of the second transistor, and the other end is connected to Vdd. - R7 connects the drain to the ground. - The output from the second stage is labeled as Vo. This circuit is designed to amplify the input signal Vin, producing an output signal Vo after passing through two amplification stages.
