A new breed of electronically adjustable resistors promises to ease fine-tuning in sensors and other electronic devices. Adjustable resistors have come a long way from mechanical potentiometers set ...

Figure 2: Power FET compact models are making the transition from a 2-terminal to a 3-terminal resistor model equivalent network to model the drain drift-region. The r3_cmc (henceforth known as ‘R3’) ...

What kinds of applications utilize precision resistor trimming? Obvious applications include setting operational-amplifier gain and offset and voltage regulator output (Fig. 1a and 1b). But there are ...

Output voltage trimming allows the user to change the output voltage of the module. This greatly enhances the functionality of modules by allowing a few select, standard modules to be applied to ...

Precision systems require a minimum impact of temperature variations on offset and gain adjustments. Unfortunately, the resistors used in these and other voltage or current calibration techniques have ...

Many current-sensing ICs are available for applications that require single-quadrant operation, where positive common-mode voltages are present and current flows in only one direction. There are also ...
