Most sensors needs some signal conditioner electronics before digitize the signal.
Few examples are:
- Piezoelectric force sensors
- Geophone
- Thermocouple, ...
- Photodiode
- Thermocouple

Depending on the electrical quantity that is meaningful for the measurement, different types of amplifiers are used:
## Charge Amplifier {#charge-amplifier}
This can be used to interface with:
- piezoelectric sensors
