Latest Patents

Ayoub Rifai holds a patent for a "System and method of digital to analog conversion using dynamic element matching." This patent describes a dynamic element matching system that includes sequential register groups, decode circuitry, and pointer control circuitry. Each register group consists of at least two registers. The decode circuitry manages the state of each register group based on the level of a digital input signal, relative positions concerning a begin pointer and an end pointer, and corresponding pseudo-random probability values. The pointer control circuitry cyclically advances the end pointer among the register groups, enabling a register within each added register group in response to increasing digital input signal levels. Conversely, it also cyclically advances the begin pointer, disabling a register within each removed register group when the digital input signal level decreases.
