+++ title = "Signal Conditioner" author = ["Dehaeze Thomas"] draft = false category = "equipment" +++ Tags : [Sensors]({{< relref "sensors.md" >}}), [Electronics]({{< relref "electronics.md" >}}) 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.md" >}})) - Charge to Voltage ([Charge Amplifiers]({{< relref "charge_amplifiers.md" >}})) - Voltage to Voltage ([Voltage Amplifier]({{< relref "voltage_amplifier.md" >}})) ## Bibliography {#bibliography}
