Latest Patents
One of Rafi's latest patents is titled "Interface between processing unit and an external nonvolatile memory." This invention discloses an interface between two devices that utilizes CMOS signaling to consume power efficiently. To achieve high speed, a reduced frequency clock is transmitted from one device to another. The second device employs a clock multiplier to recreate the original clock, ensuring synchronization. Additionally, both devices utilize a clock phase alignment block that aligns the clock phase with incoming data, employing a digital PLL to minimize power consumption. This interface is capable of transmitting serial data at rates up to and exceeding 2.5 Gbits/sec.
Another significant patent is "Wireless communication system and method using digital calibration to control mixer input swing." This invention addresses the control of the voltage swing of a local oscillator (LO) signal in a wireless communication device. By preventing overstressing of semiconductor devices in a mixer, Rafi's design enhances the reliability of the system. The quadrature divider supplies the LO signal to the mixer, while digital calibration methodology regulates the current drawn from the power supply to set the voltage swing of the LO signal.
