If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

My last column converted an imperfect receiving device into an ideal termination using a constant-resistance network (Reference 1). The schematic in Figure 1 extends that idea, combining a good ...

This simple but clever continuity tester sports two LEDs: RED LED = circuit resistance is < approx 10K, GREEN LED = circuit resistance <10Ω. It consumes approx 8mA from a 9V battery. When not ...

Though not difficult, driving a load from a voltage reference IC requires some attention. After determining the supply voltage and output voltage, various other design parameters need to be considered ...

Pulse-width-modulation (PWM) duty cycles above 50% require a compensating ramp — called slope-compensation — to avoid instability. With traditional slope-compensation solutions, it is difficult for ...
