Normally you’d throw in some resistors to form different voltage dividers depending on which key is pressed, and read the resulting voltage off of a voltage divider with an ADC. But that means ...

Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...

The two resistors may have fixed values or one may be an LDR, a thermistor or other input device. The supply voltage is divided in the ratio of the resistances in the voltage divider. For the ...

First find the total resistance of the voltage divider. If the thermistor is moved to a freezer its resistance rises to \(40k\Omega\). The resistance of the resistor remains the same. We can ...

One significant advancement is the development of a high-performance squarer-divider circuit that operates at a very low voltage of 0.7 V. This circuit employs a MOS translinear loop (MTL ...
