    Abstract: The present invention is directed to signal processing system and electrical circuits. According to various embodiments, a DLL system includes a delay line provides multiple output signals associated with different clock phases. The delay line may be adjusted using a pair of bias voltages. A phase detector systems generates the bias voltages using the multiple output signals from the delay line. The multiple output signals include signals associated with the first phase, the last phase, and two adjacent phases. There are other embodiments as well.

    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.
