    摘要: A filter that has a resonator operated in series resonance and a two-pole terminal resonator circuit with a resonator whose electric conductance can be divided into a useful component and a parasitic component. A first differential stage actuated by a signal source and having two active elements whose ground connections are each linked to a respective current source and to a respective connection of the two-terminal resonator. A compensation circuit having two connections and which simulates the parasitic component of the resonator electric conductance is connected to a second differential stage which actuated by the signal source, is of the same type as the first differential stage, and has two active elements whose ground connections are each linked to a respective current source and to a respective connection of the compensation circuit. An evaluation circuit is linked to the two mutually reversed, i.e. connected in phase opposition, output connections of the two differential stages.

    摘要: In accordance with the present invention, two unsymmetrical differential amplifier stages are fed from a common signal source that supplies an AC voltage signal, but to which the two differential amplifier stages are connected with respect to the unsymmetry in opposite senses. The outputs of the two differential amplifier stages, however, are connected with respect to the unsymmetry in like sense and to an output circuit that provides the load resistances and whose output supplies the rectified a.c. voltage signal that also has an approximately quadratic characteristic.

    摘要: Conventional integrable differential amplifiers have implanted resistors as load resistors, the limited size of which represents a barrier for the minimization of current consumption. In accordance with the present invention, the load resistors are replaced by load elements that represent non-linear two-terminal elements such as diodes, the potential at these load elements is held constant via a control loop by a controlling element such as a control transistor. This allows the current consumption of differential amplifier stages to be reduced to the order of magnitude of the residual current without increasing the area required for integration of the circuit.
