<p>Between the inverting output (5) and the non-inverting input (2) of a fully balanced amplifier (1) a first junction capacitor (C1) is arranged and between the non-inverting output (4) and the inverting input (3) a second junction capacitor (C2) is arranged. Further, a first resistor (R1) is arranged between a first input terminal (6) and the non-inverting input (2) and a second resistor (R2) is arranged between a second input terminal (7) and the inverting input (3). A first current source (I1) is connected to the non-inverting input (2) and a second current source (I2) is connected to the inverting input (3). The current sources (I1, I2) produce the reverse voltages for the junction capacitors (C1, C2) across the resistors (R1, R2) to define the capacitance values of these capacitors.</p> |
