2.3.1.2 Active Current Measurement

To measure active current in a profile form, TI recommends using a 0.1-Ω 1% 0603 resistor on the board, and

measuring the differential voltage across the resistor. This measurement can be done using a voltmeter or an

oscilloscope for measuring the current profile for both power supplies (3.3 V or 1.8 V).

Jumper J15 shunt is removed and a 0.01 resistor is populated in parallel to measure the active currents on the

1.8V supply (see

Figure

2-8). Similar operation with J16 and 3.3V supply.
