An Logarithmic amplifier is good example of why we need to be careful to call these types of devices analog, not linear devices – because these are certainly not linear. Log amps can be a ...

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 ...

Plessey Semiconductors has announced the launch of a logarithmic/limiting amplifier with 75dB dynamic range. The PS13201 log amp is a pin for pin, drop in compatible replacement for the original ...

It’s a staple of spy thriller movies, that the protagonist has some kind of electronic scanner with which he theatrically searches his hotel room to reveal the bad guys’ attempt to bug him. The bug of ...
