摘要： A circuit includes first and second transconductance stages that generate first and second currents, respectively, in response to an input signal. A current combiner circuit selectively couples the first current to a first output, selectively couples the second current to the first output, selectively couples the first current to a second output, and selectively couples the second current to the second output. In response to the first current being coupled to both the first and second outputs, the current combiner circuit couples the second current to both the first and second outputs. In response to the first current being decoupled from the second output, the current combiner circuit decouples the second current from both the first and second outputs. In response to the first current being decoupled from the first output, the current combiner circuit decouples the second current from both the first and second outputs.

摘要： A cross-differential amplifier is provided. The cross-differential amplifier includes an inductor connected to a direct current power source at a first terminal. A first and second switch, such as transistors, are connected to the inductor at a second terminal. A first and second amplifier are connected at their supply terminals to the first and second switch. The first and second switches are operated to commutate the inductor between the amplifiers so as to provide an amplified signal while limiting the ripple voltage on the inductor and thus limiting the maximum voltage imposed across the amplifiers and switches.

摘要： A power amplifier arrangement includes a power amplifier with an input for a radio-frequency signal and an output for delivering a second radio-frequency signal. The second radio-frequency signal has a current and a voltage. A second element is configured to deliver a first signal derived from the current of the second radio-frequency signal. Furthermore, a first element is provided to deliver a second signal derived from the voltage of the second radio-frequency signal. An evaluating circuit detects in-phase components of the first and the second signal. As a result, in-phase current and voltage components can be detected together which produce the active power of the second radio-frequency signal by multiplication.

摘要： A differential amplifier can include input transistors for receiving a differential input signal and an inductor connected to the input transistors. The inductor can protect a voltage supply from radio frequency in the differential input signal. The accuracy of this differential amplifier can be significantly improved by including a bias network. This bias network advantageously allows a bias current in the input transistors to be set independently of a voltage drop across the inductor.

摘要： The present invention relates to a method and circuit arrangement for adjusting a gain, wherein said circuit arrangement comprises at least a first output branch connected to a first load and a second output branch connected to a second load. The gain control function is realized based on a current splitting, wherein a non-operated output branch is used as a kind of dummy branch for receiving a part of the output current. Thus, only as many output branches as there are outputs are required to implement a gain control based on splitting. Thereby, a complexity of the layout design is reduced and control and biasing of dummy branches is not required.

摘要： An amplifier circuit (15) amplifies a differential signal supplied by a pair of input terminals ( {P1+, P1−}). A phase controller circuit (25) is placed between the emitters of bipolar transistors (101a, 101b) and the ground. A feedback circuit (35) is placed across the input and the output of the amplifier circuit (15) for feeding the output of the amplifier circuit (15) back to the input thereof. A phase change amount in the amplifier circuit (15) is determined by the values of inductors (201a, 201b), whereas a phase change amount in the feedback circuit (35) is determined by the values of resistances (301a, 301b) and capacitors (302a, 302b). The values of these devices are selected so that a phase difference between an input signal and a feedback signal is approximately 180 degrees in a range from the frequency of a fundamental wave of the input signal to the frequency of a second harmonic thereof.
