<p>The oscillator (1) has the battery voltage (U B) is connected across the operational amplifier (6). The input terminals of the operational amplifier are connected to the terminals (4,5) of the resonant oscillator circuit (2). The circuit consists of an inductor (L S), capacitor (C S) and resistor (R S) in parallel. One of the terminals provides an offset voltage (U off). The other terminal is connected via a resistor (R1) to the output (6) of the operational amplifier.</p> |
