In this post, we will take a gentle dive into logarithmic amplifiers—commonly known as log amps—those quietly powerful circuits that work behind the scenes to decode exponential signals and tame wide ...

The basic anti-log amplifier looks like the familiar circuit of Figure 1. The approximate equation for V 0 given in Figure 1 comes from the Ebers-Moll model. A more advanced model employed by many ...

Download this article in PDF format. Logarithmic amplifiers with their log functionality are useful for compressing wide dynamic-range signals whereby the measured quantities are in decibels (dB).

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
