Abstract :
An continuous-time inductorless non-linear equalizer is presented which can be programmed for different channels. The circuit can be adapted to a given link environment (noisy channel and the termination) by controlling the amount of feedback and thereby defining the high-frequency and low-frequency response. The architecture is scalable to higher speeds with technology. Measurement results depict the successful equalization of channels having an attenuation of upto -19 dB at 10 GHz. The circuit is fabricated in 0.13 μm CMOS technology and consumes a current of 39 mA (max.) at (V dd = 1.32 V).
