Measure small currents without adding resistive insertion loss
by Maciej Kokot @ edn.com: In most cases, you measure current by converting it into a proportional voltage and then measuring the voltage. Figure 1 shows two typical methods of making the conversion. In one method, you insert a probing resistor, RP, in series with the current path...
