AMPLIFICADOR DE DISTORSION PARA COMPENSAR LA ATENUACION DEPENDIENTE DE LA FRECUENCIA DE UNA LINEA DE TRANSMISION; Y METODO ASOCIADO.

摘要

A multi-stage differential amplifier and method provides a gain versus frequency warping response characteristic that equalizes a transmission line of a given length to compensate for frequency-dependent attenuation. The warping response characteristic comprises the inverse of the attenuation versus frequency characteristic of the line, and affords a substantially flat system gain response over a predetermined frequency spectrum. The individual amplifier stages employ operational amplifiers, and are designed using SPICE simulations such that the individual responses of the stages are tailored so they combine to provide the required overall warping response to compensate the line.
