Latest Patents

One of his latest patents is for an adaptive analog transversal equalizer. This invention is designed for use in the filtering system of a disc drive PRML read channel. The transversal equalizer employs non-ideal delay elements to enhance performance. The filtering system includes the equalizer connected in series with an adaptive analog prefilter. The prefilter consists of multiple serially connected adaptive analog filter stages, each with variable transfer functions determined by adaptive parameter signals. Additionally, the generalized transversal equalizer features several serially connected adaptive analog low pass filters, equipped with taps on either side. It also includes multipliers that receive signals at the tap locations and a summing circuit that processes the outputs. The transfer functions of the delay circuit are continuously variable, adapting to the parameter signals received.

Another significant patent is for fully integrated programmable filters for disc drive subsystems. This invention encompasses a disc drive system that includes various subsystems, with at least one subsystem featuring a filter that is completely integrated using a synthetic integrated circuit element.
