- Figure 1. This method for measuring high-side supply current requires an auxiliary transistor
- Figure 2. This circuit uses the negative-supply current of the op amp to measure the high-side supply current
- Figure 3. Because of the positive-supply current, the measured values (dots) do not agree well with the theoretical values (straight line)
- Figure 4. Gain compensation by adjusting RC improves the accuracy of the measurement
