Abstract
An adaptive continuous-time linear equalizer (CTLE) includes a CTLE cell including input terminals and output terminals, a low-pass filter configured to respectively output low-band differential signals obtained by respectively low-pass filtering differential output signals, and an error amplifier configured to amplify a difference between the low-band differential signals and output the difference as a control voltage. The CTLE cell includes first and second transistors each including an input terminal and an output terminal and an offset compensator configured to adjust a potential difference between a supply voltage source and the output terminal according to the control voltage.
