Thermistors make good choices as temperature sensors when you need fine resolution over a relatively small temperature span. Unfortunately, a thermistor’s resistance-temperature curve has a nonlinear ...

One of the most predictable non-linear elements commonly available is the bipolar transistor. The relationship between collector current and emitter base voltage is precisely logarithmic from currents ...

Logarithmic amplifiers with their log functionality are useful for compressing wide dynamic-range signals whereby the measured quantities are in decibels (dB). They’re used in a wide variety of ...
