Latest Patents

One of his latest patents is a method for selecting a sequence of cells inside a bidimensional matrix. This invention relates to a method for selecting a sequence of cells of current sources within a cell matrix structure of a digital-analog converter. The method utilizes symmetries concerning the center of a rectangular or square matrix structure, a symmetry point located at a quarter of the length of a diagonal from the center, and one of the two mean perpendiculars of the structure. This approach is designed for selecting the mapping areas for the consecutive cells.

Another significant patent is the linear tunable Gm-C integrator. This invention features a time-continuous tunable Gm-C integrator that includes a 'super Gm' differential input stage. It employs linear and constant degeneration resistors to achieve optimal linear input-voltage to output-current conversion. The integrator is equipped with three tuning CMOS transistors that control the integrating currents flowing between the input stages and towards the outputs. This design allows for a perfectly linear transconductance characteristic over the entire operating range of the integrator.
