A 10 Gbit/s adaptive CTLE based on spectrum balancing was designed. The bandwidth and gain of the linear equalizer were improved by inductor parallel peaking and source degradation techniques. In order to extend the rate range of adaptive CTLE based on spectrum balancing, the cut-off frequency of low frequency and high frequency was adjusted simultaneously by the active hybrid filter. Meanwhile, the mismatch error was reduced by DC offset cancellation loop (DCOC). The simulation was carried out by TSMC 018 μm CMOS process. The results showed that the 10 Gbit/s PRBS7 signal was transmitted through an 4572 cm FR4 backplane with a loss of 15451 dB at the Nyquist frequency, and after equalization with equalizer, the eye opening reached 05 UI.
