This letter introduces a neutralization technique of degradations caused by RC and LC passive effects in the microelectronic systems. It is based on the use of the negative group delay (NGD) circuits. For the RC-effect, a 1st order NGD cell operating in base band is used. To cancel the RLC effects, a 2nd order NGD cell was proposed. The feasibility of the technique is confirmed by simulations and experimentations with circuits implemented in hybrid technology.
