Latest Patents

Among his latest patents, Prete has introduced groundbreaking technologies such as receiver equalization circuitry using variable termination. This invention focuses on systems, apparatuses, and methods for performing efficient data transfer in computing systems. The technology involves multiple transmitters sending single-ended data signals to various receivers. To address noise issues associated with single-ended signaling, the receivers incorporate equalization circuitry and termination circuitry. This setup prevents reflection on the transmission line ending at the receiver, while the equalization circuitry employs a bridged T-coil circuit to provide continuous time linear equalization (CTLE) without a feedback loop. Additionally, the equalization circuitry includes a high-pass filter that offsets the low-pass characteristics of the transmission line. A comparator within the receiver compares the input signal to a reference voltage, with its placement and the inductance ratio of the bridged T-coil circuit being contingent on the presence of self-diagnostic circuitry.

Another notable patent involves periodic receiver clock data recovery with dynamic data edge paths. This invention outlines systems, apparatuses, and methods for implementing a periodic receiver clock data recovery scheme. The IQ link calibration scheme performs a non-destructive data and edge path switch to determine an IQ offset without disturbing the data. The data path and edge path traverse multiple stages of deserializers to widen the data path, with the deserializers clocked by clock-divided versions of the original data and edge clocks. The calibration routine begins by aligning the edge clock with the data clock, followed by swapping the data and edge paths at a common point in a slower clock domain. After calibrating the data path, the edge and data paths are reverted to their original configuration.
