Abstract:
The present invention is directed to electrical circuits and techniques thereof. In various embodiments, the present invention provides a variable gain amplifier architecture that includes a continuous-time linear equalizer (CTLE) section and a variable gain amplifier (VGA) section. The CTLE section provides both a pair of equalized data signals and a common mode voltage. A DAC generates a control signal based on a control code. The VGA section amplifies the pair of equalized data signals by an amplification factor using a transistor whose resistance value is based on both the common mode voltage and the control signal. There are other embodiments as well.

Claim (Index 11):
A variable gain amplifier device comprising:\n a first transistor and a second transistor, the first transistor comprising a first gate terminal coupled to a first input signal and a first drain terminal coupled to a first output node, the second transistor comprising a second gate terminal coupled to a second input signal and a second drain terminal coupled to a second output node; a first common mode resistor coupled to the first output node; a second common mode resistor coupled to the second output node and the first common mode resistor; a common node configured between the first common mode resistor and the second common mode resistor, the common node is characterized by a common mode voltage; a third transistor and a fourth transistor, the third transistor comprising a third gate terminal coupled to the first output node and a third drain node coupled to a third output node, the fourth transistor comprising a fourth gate terminal coupled to the second output node and a fourth drain terminal coupled to a third output node; and a fifth transistor comprising a fifth gate terminal coupled to a control voltage and the common node between the first common mode resistor and the second common resistor, the fifth transistor being configured between the third transistor and the fourth resistor, the resistance value based on the control voltage and the common node voltage.
