A curve tracer is a test instrument that plots the v-i characteristic of a device. In this lab you'll build a curve tracer and use it to explore the v-i characteristics of a mosfet. The schematic below shows a simple circuit that will plot the v-i characteristic of a resistor when a transient analysis is run. Please observe that The Vtest voltage source generates a triangle waveform that ramps from 0V to 3V then back again over a period of 1ms. The stop time of the transient analysis is chosen to be 0.5ms so that the voltage on node vtest will be just the rising ramp from 0V to 3V.
