Question
### NMOS Amplifier Design Analysis A conceptual design of an NMOS amplifier is presented. The task is to determine the DC bias current, \( I_D \), expressed in milliamps, using the given parameters: - Threshold Voltage (\( V_t \)) = 0.9 volts - Transconductance Parameter (\( k \)) = 0.4 mA/V\(^2\) - Bias Voltage (\( V_{GS} \)) = 2.3 volts - Supply Voltage (\( V_{DD} \)) = 6.5 volts - Drain Resistance (\( R_D \)) = 2 kΩ #### Circuit Diagram Explanation The circuit involves: - A voltage source \( V_{GS} \) connected to the gate of the NMOS transistor, establishing the gate-source voltage. - A resistor \( R_D \) is connected between the drain of the transistor and the supply voltage \( V_{DD} \). - The current \( i_D \) flows from \( V_{DD} \) through \( R_D \) and the NMOS transistor to ground, with a corresponding drain-source voltage \( v_{DS} \). Your task is to calculate and express the DC bias current \( I_D \) using the given parameters. #### Your Answer: Please provide your calculated value of \( I_D \) in milliamps.
