Inverting mode amplifier is needed by precision accelerometers because that usually charge output device. This amplifier is used to convert charge into voltage output. Here is an example of accelerometer with DC servo. C1 is used to convert the charge from the transducer into voltage, which should equal the input capacitance of the op amp plus the transducer capacitance. The […]

We can create Crystal Colpitts oscillator using a parallel mode crystal and a transistor. The circuit shown by the following figure As an inductance, this circuit uses crystal. The crystal circuit consist of a large value capacitive divider that is used between gate, a small series capacitor, ground, and source. Component’s values that we choose must produce a highest ratio […]
