Abstract:
The present invention is directed to electrical circuits. More specifically, embodiments of the present invention provide a variable gain amplifier (VGA) device that includes a low-gain tuning section and a high-gain tuning section. The low-gain tuning section includes both resistor and transistor elements. The high-gain tuning section includes a transistor element and is activated when an output gain is greater than a predetermined threshold level. There are other embodiments as well.

Claim (Index 18):
An electrical system for adjusting signal gain, the system comprising:\n an amplifier circuit comprising:\n a first input transistor comprising a first terminal and a second terminal and a third terminal, the first input transistor being configured to receive a first input voltage at the first terminal; \n a second input transistor comprising a fourth terminal and a fifth terminal and a sixth terminal, the second input transistor being configured to receive a second input voltage at the fourth terminal; \n a first load being coupled to the fourth terminal and the first output terminal; \n a second load being coupled to the fifth terminal and the second output terminal; \n a control module being configured to generate a first tuning signal and a second tuning signal, the second tuning signal being at a low-gain setting if a gain setting for the VGA is lower than a first predetermined threshold value; \n a first tuning section comprising a first resistor and a first tuning transistor, the first tuning transistor being coupled to the first tuning signal, the first tuning section being coupled to the third terminal and the sixth terminal; and \n a second tuning section comprising a second tuning transistor, the second tuning section being coupled to the second tuning signal, the second tuning section being coupled to the third terminal and the sixth terminal; \n wherein the first tuning signal changes an impedance value of the first tuning transistor, the impedance value of the first tuning transistor being predetermined; and an interface.
