Continuous time linear equalizer

A method comprising:

• receiving, by a summation node, complementary current summation signals of a first controllable transconductance unit and a second controllable transconductance unit,
• wherein a first signal path comprises a high pass filter and the first controllable transconductance unit;
• wherein a second signal path comprises a second controllable transconductance unit;
• and
• receiving, by the high pass filter, an input signal on a first port of the high pass filter,
• wherein the high pass filter comprises a second port coupled to a control port of the first controllable transconductance unit and a third port coupled to the summation node.

A system comprising:

• a first signal path comprising a high pass filter and a first controllable transconductance unit;
• a second signal path comprising a second controllable transconductance unit;
• and
• a summation node configured to receive complementary current summation signals of the first transconductance unit and the second transconductance unit;
• wherein the high pass filter is a first order high pass filter comprising,
• a resistor,
• a capacitor,
• a first port configured to receive an input signal,
• a second port coupled to a control port of the first transconductance unit, and
• a third port coupled to the summation node,
• wherein adjusting at least one of the capacitance of the capacitor or the resistance of the resistor controls a transfer function of the system.
