Zeus MOSFET Matching
Mosfets mounted on an aluminium plate.
L200 current source mosfet matching circuit.
-
Use 12 volts for IC1 (STMicroelectronics
L200) Vsupply.
-
Digital voltmeter to three decimal places at 2 to 6 volts
recommended.
-
Current set to 500mA (higher current cause device heating).
-
Mount DUTs on common heatsink as per picture.
-
Allow reading to stabilize (about 10 seconds) before noting
value.
-
Once close matches have been ascertained retest those matches
to get best fits.
