Abstract
The present description concerns a variable-gain amplification device and a variable-gain amplification method, in which a segmentation of a current switching is implemented in at least two parts.
Claims20
A variable gain amplification device comprising:
- a current switching segmented into at least two parts.
A phase shifting device comprising:
- a first device comprising a first current switching segmented into at least two first parts, the first device configured to apply a first gain to a first signal;
- a second device comprising a second current switching segmented into at least two second parts, the second device configured to apply a second gain to a second signal in quadrature with the first signal, the first and second gains determining a phase-shift value;
- and
- an in-phase/quadrature-phase (I/Q) modulator configured to provide the first and second signals.
