Continuous time linear equalizer with active inductor

A method comprising:

• receiving an input signal at a continuous time linear equalizer;
• and
• generating, by the continuous time linear equalizer, an equalized signal based on the input signal, the continuous time linear equalizer having a transfer function that comprises a first pole, a second pole, a third pole, a first zero, and a second zero, the continuous time linear equalizer comprising an equalizer portion and an active inductor portion, the active inductor portion operatively coupling a load of the equalizer portion to a current source, the active inductor portion being configured to implement the first zero and the second zero of the transfer function, the equalizer portion being configured to implement the first pole, the second pole, and the third pole of the transfer function, the first zero being associated with a first input frequency of the transfer function, the second zero being associated with a second input frequency of the transfer function, the first pole being associated with a third input frequency of the transfer function, the second pole being associated with a fourth input frequency of the transfer function, the third pole being associated with a fifth input frequency of the transfer function, the first input frequency being less than the third input frequency, the third input frequency being less than the second input frequency, and the second input frequency being less than the fourth input frequency and the fifth input frequency.
