Document Type and Number:
Japanese Patent JP2003504907
Kind Code:
A
Abstract:
A circuit configuration is configured such that selectively a first amplifier or a second amplifier amplifies signals. The second amplifier is operated depending on the conditions established at the input terminal of the first amplifier. A switching element has a controlled path connected to an input terminal of the second amplifier. The switching state of the switching element can be controlled by the input terminal of the first amplifier. As a result, it is possible to effect the changeover between the amplifiers with minimal outlay and without disturbing the amplifiers.
