ECE 322L: Microelectronics Lab Lab #7: NMOS Amplifier Objectives: Investigate the properties of a very simple amplifier made with an NMOS transistor. Materials: Voltmeter Voltage supply (continuously adjustable 0V to 5V) Voltage supply (fixed 5V) Solderless breadboard Hookup wire One 330 resistor One 3.3k resistor One ZVN3306A NMOS transistor Setup: Construct the circuit below using a ZVN3306A NMOS transistor and 330 resistor. The center lead on the ZVN3306A is the gate. Background: The circuit shown in "Setup" is identical to the one used as a digital NMOS inverter in lab #6. In that lab, the input signal V i was either 0V or 5V to represent a logic 0 or 1. The output V o was either very close to 0V or very close to 5V (a logic 0 or 1). In this lab we will investigate applying intermediate voltages between 0V and 5V and show that changes in the input voltage may result in either larger or smaller changes in the output voltage. In other words, this same circuit can be viewed as an amplifier. In other words, V o = A V i , where A is the (possibly negative) amplification.
