Question
A conceptual design of an NMOS amplifier is shown below. For this amplifier, the threshold voltage \( V_T \) is 0.8 volts, the transconductance parameter \( k \) is 0.4 mA/\( V^2 \), the gate-source voltage \( V_{GS} \) is 2.3 volts, the supply voltage \( V_{DD} \) is 5.5 volts, and the drain resistor \( R_D \) is 2 kΩ. The question asks: what is the DC bias current, \( I_D \), expressed in milliamps? **Diagram Explanation:** - The circuit consists of an NMOS transistor. - The gate-source voltage (\( V_{GS} \)) is applied between the gate and source of the NMOS. - There is a resistor (\( R_D \)) connected between \( V_{DD} \) and the drain of the transistor. - The drain current (\( i_D \)) flows through the resistor \( R_D \). - The output voltage (\( v_{DS} \)) is taken from the drain. The goal is to determine the DC drain current \( I_D \) in milliamps using the given parameters.
