Abstract:
An integrated circuit for high speed signal processing, the integrated circuit comprising:a first differential amplifier receiving a set of differential input signals having a frequency, a second differential amplifier coupled to the first differential amplifier, each of the first and second differential amplifiers including a number of transistors and resistors, each of the transistors associated with a value of an Electrically Equivalent Geometry (EEG) controlling an electrical current going through the each of the transistors, wherein a ratio for each of the transistors is determined to be the EEG of the each of the transistors over the EEG of a chosen one of the transistors, and wherein the ratio for each of the transistors is adjusted in reference to the frequency of the input signal so that a first ratio set including the ratio for each of the transistors in the first differential amplifier is different from a second ratio set including the ratio for each of the transistors in the second differential amplifier.
