Abstract:
1. A front-end equalizer and amplifier circuit, comprising a first pair of fully differential pair transistors and a second pair of fully differential pair transistors, wherein a first end of a first transistor of said first pair is connected with ground through a first tail current, a second end of said first transistor of said first pair is connected with a power supply through a first inductive load and a negative output, and a third end of said first transistor of said first pair is connected with a positive input; wherein a first end of a second transistor of said first pair is connected with ground through a second tail current, a second end of said second transistor of said first pair is connected with a power supply through a second inductive load and a positive output, and a third end of said second transistor of said first pair is connected with a negative input; wherein said first end of said first transistor of said first pair is connected with said first end of said second transistor of said first pair through a capacitive component; wherein a first end of a first transistor of said second pair is connected with ground through a third tail current, a second end of said first transistor of said second pair is connected with said negative output, and a third end of said first transistor of said second pair is connected with said positive input; wherein a first end of a second transistor of said second pair is connected with ground through a fourth tail current, a second end of said second transistor of said second pair is connected with said positive output, and a third end of said second transistor of said second pair is connected with said negative input; wherein said first end of said first transistor of said second pair is connected with said first end of said second transistor of said second pair through a resistive component.
