**Problem 6: NMOS Transistor Analysis** Given an NMOS transistor with the following parameters: - Threshold Voltage (\(V_t\)) = 1.75V - Transconductance Parameter (\(k_n\)) = 25 mA/V\(^2\) - Channel Length Modulation (\(\lambda\)) = 0 And consider the provided circuit diagram. **Tasks:** a) For an operating point with \(V_O = 3.5V\) and \(I_D = 10 \, mA\), determine the range of \(R_S\) values needed to keep the transistor in the saturation region. b) Given \(R_S = 100 \, \Omega\), compute the resistances \(R_D\), \(R_{G1}\), and \(R_{G2}\) required to achieve \(V_O = 3.5V\) and \(I_D = 10 \, mA\). **Circuit Explanation:** - The circuit consists of an NMOS transistor, with a drain connected to \(R_D\) and a source connected via \(R_S\). - The gate voltage is determined by the resistive divider \(R_{G1}\) and \(R_{G2}\). - The supply voltage (\(V_{DD}\)) is +10V. **Analysis Objective:** 1. Identify operating region constraints for transistor saturation. 2. Solve resistor values for desired voltage and current conditions.
