Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “ DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to ...

Overload limiting comes from an npn transistor whose Vbe is the resistor voltage, pulling down the gate with its collector. The firm has a more detailed description of the precision current interface ...
