Generate Transistor Curves with Power Supply
白皮书
When your lab lacks a dedicated transistor curve tracer use a power supply instead. A bench power supply with multiple outputs can generate a set of transistor curves for a metal–oxide–semiconductor field-effect transistor (MOSFET). A MOSFET is a field-effect transistor (FET) used for switching signals in electronic devices. A power supply with two positive outputs can test an N-channel FET, such as the popular 2N7000. An alternative is the BS170 N-channel MOSFET as it is very similar but has a higher drain current making it a more robust choice.
