Designs of integrated circuits for high-speed signals and methods therefor

A system for high speed signal processing, the system comprising at least a first-building block and a second building block, the first and second building blocks are coupled to provide a desired function, each of the building blocks having identical circuit topology and including:

• a first differential amplifier,
• 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;
• p1 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;
• wherein the ratio for each of the transistors is adjusted to 1) minimize parasitic effects that cause artifacts to output signals, and 2) form resonant effects to provide filtering functions to minimize harmonic components in the output signals.
