Continuous time linear equalization for current-mode logic with transformer

A method for equalizing signals using a common-mode logic (CML) device, the method comprising:

• receiving a pair of differential input signals using a pair of input transistors, the pair of input transistors including a first transistor, the first transistor including a first source terminal and a first drain terminal;
• receiving a bias control signal;
• configuring a capacitor module using at least the bias control signal, the capacitor module being coupled to the first source terminal;
• receiving a first equalization signal;
• adjusting a first peaking level of a first equalizer module using the first equalization signal;
