Abstract :
An 11 Gb/s Equalizer is designed in 45 nm CMOS to compensate for the losses in a 12rdquo PCB trace. Amplitude variations are compensated with a limiting amplifier that provides a constant swing to a digital phase detector. An offset cancellation loop is used to attenuate offset in the high gain stage.
