You would still need to find a current sense amplifier that meets the needs of 60uA measurement, which I agree, INA901 is not the best fit for. INA190 is an ideal device for measuring this level of current, but unfortunately this device is not available in ...

the measurement tempco is low, being limited to the mechanical and magnetic temperature coefficients of the meter movement. At higher currents though, we are seeing the voltage across the diode, which of course decreases by about 2mV/K as predicted by the diode equation. This not only affects ...
For some reason the signal there has a reverse slope in every second cycle (QC, QB conducting). Please note the new schematic, with the colored numbers I have marked the measurement points of the signals. (I tried with different types and core sizes of TCS2 - same result ) I found ...
When using a single pair of leads to measure very low ohms, the resistance of the measuring wires and voltage drops across the various joints become substantial enough to invalidate your measurement. The solution is to use the “Kelvin method” or 4-wire measurement. This involves passing a hi...
ISENSE transitions from a base of 60 mA to a higher value of 220 mA enabled by a momentary switch that brings in more parallel load resistance. There is no zero ISENSE measurement, because it is already shown that the MOSFET gain is too low in that case....
Modeling includes the gate-drive output parasitics, power MOSFET intrinsic parameters, PCB parasitics, and load parasitics. To evaluate the methodology, LTspice simulation and experimental results are studied. 展开 关键词: Integrated circuit modeling Junctions MOSFET Semiconductor device modeling ...

Since current–voltage characteristics are usually measured using separate sense contacts for the voltage measurement, the position and number of these contacts may considerably affect the shape of the resulting current–voltage characteristic and, thus, the fill factor. By means of simulations with the...
