Abstract:
A continuous-time linear equalizer for use in a receiving unit of a high-speed data transmission system for receiving an input signal includes a signal line configured to provide an equalized output voltage, and an active peaking control unit, including a predetermined first number of active peaking transistors each coupled between the signal line and a power supply rail; a peaking resistor that couples gate terminals of each of the active peaking transistors to the signal line; and a first number of first setting switches each associated with each of the first number of active peaking transistors to activate a predetermined number of the first number of transistors according to first setting signals.
