Latest Patents

One of his latest patents is for an "In-phase and quadrature decision feedback equalizer." This invention provides an apparatus and method for equalizing a dispersive channel based on in-phase and quadrature samples corresponding to an input signal. The equalizer utilizes a novel adaptation algorithm to adjust filtering characteristics based on previous in-phase samples and a current quadrature sample. This adaptation algorithm updates filter coefficients in response to detecting a transition in the in-phase samples, effectively addressing quadrature post-cursor intersymbol interference (ISI) components of the input signal. Additionally, the equalizer can also equalize in-phase post-cursor ISI components, quadrature precursor ISI components, in-phase precursor ISI components, or a combination of these.

Another significant patent is for "Systems and methods for actively-peaked current-mode logic." This invention describes a method and apparatus for creating high-speed logic circuits in a CMOS environment using current steering logic cells with actively-peaked NMOS or PMOS loads. The logic cells can include buffers, AND gates, OR gates, flip-flops, and latches. The current steering cells with actively-peaked loads provide benefits such as reduced power consumption, smaller area, and higher speed performance compared to conventional devices. This performance enhancement is achieved using NMOS followers with resistively degenerated gates to create a frequency peaked transfer function of current-mode logic cells.
