Summary
| Description |
English: Principle circuit of a charge amplifier with a piezoelectric sensor at the input. Main components are the operational amplifier and the feedback capacitor Cf. The feedback resistor Rf sets the lower frequency limit. Cinp is the input capacitance which is not required as component. Cc is the capacitance of the sensor cable.
Deutsch: Prinzipschaltung eines Ladungsverstärkers mit einem piezoelektrischen Sensor am Eingang. Hauptbestandteile sind der Operationsverstärker und der Rückkoppelkondensator Cf. Der Rückkoppelwiderstand Rf bestimmt die untere Grenzfrequernz. Cinp ist die Eingangskapazität und nicht als Bauteil erforderlich. Cc ist die Kapazität des Sensorkabels. |
