AMPLIFIER HAVING STACKED CURRENT-DRIVEN CURRENT DRIVERS |
摘要 |
According to a particular example application, the present invention is embodied in the form of first and second current-steering sections arranged to steer a differential current input signal. Each of the first and second current-steering sections is current driven via differential current paths. The first current-steering section configured and arranged to source current and thereby drive the second current-steering section. Another aspect of the invention employs stacked Gilbert cells, as described above, to form a variable gain amplifier ("VGA") circuit that achieves a large dynamic range, a wide frequency response and improved linearity, while consuming relatively low amounts of power. |
