Most sensors needs some signal conditioner electronics before digitize the signal. Few examples are:

  • Piezoelectric force sensors
  • Geophone
  • Photodiode
  • Thermocouple

The signal conditioning electronics can have different functions:

  • Amplification
  • Isolation
  • Filtering
  • Excitation
  • Linearization

Depending on the electrical quantity that is meaningful for the measurement, different types of amplifiers are used:

  • Current to Voltage ([Transimpedance Amplifiers]({{< relref "transimpedance_amplifiers" >}}))
  • Charge to Voltage ([Charge Amplifiers]({{< relref "charge_amplifiers" >}}))
  • Voltage to Voltage ([Voltage Amplifier]({{< relref "voltage_amplifier" >}}))
