Latest Patents

Fraser holds a patent for a "Multi-stage differential warping amplifier and method." This invention 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, which 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 to ensure that their responses combine effectively to achieve the desired overall warping response.
