  • Oscillator circuit for a sensor
    Patent number: 7561000
    Abstract: An oscillator circuit for a sensor, with a tuned circuit and an operational amplifier, the electrical oscillation of the tuned circuit is capable of being tapped between a first terminal and a second terminal of the tuned circuit, and the first terminal of the tuned circuit being connected to the noninverting input of the operational amplifier and the output of the operational amplifier is fed back to the noninverting input of the operational amplifier. The oscillator circuit is designed to improve the dynamic behavior of the oscillator circuit by the second terminal of the tuned circuit —at least in terms of AC voltage —being directly connected to the inverting input of the operational amplifier.
    Type: Grant

  • Oscillator circuit for a sensor
    Publication number: 20060012443
    Abstract: An oscillator circuit for a sensor, with a tuned circuit (2) and an operational amplifier (3), the electrical oscillation of the tuned circuit (2) is capable of being tapped between a first terminal (4) and a second terminal (5) of the tuned circuit (2), and the first terminal (4) of the tuned circuit (2) being connected to the noninverting input of the operational amplifier (3) and the output (6) of the operational amplifier (3) is fed back to the noninverting input of the operational amplifier. The oscillator circuit is designed to improve the dynamic behavior of the oscillator circuit by the second terminal (5) of the tuned circuit (2)—at least in terms of AC voltage—being directly connected to the inverting input of the operational amplifier (3).
