Abstract
Provided is a digital-to-analog converter configured to mitigate data dependent jitter of switch driver signals. The digital-to-analog converter is configured to produce data patterns of “0001000”. The digital-to-analog converter includes a digital portion that includes a digital data input component, an analog portion, and a conversion component. The conversion component includes a decoder configured to split a first data stream comprising a set of digital data into a first data sub-stream and a second data sub-stream, and a second data stream comprising another set of digital data into a third data sub-stream and a fourth data sub-stream. The conversion component also includes a first pair of drivers, a second pair of drivers, a third pair of drivers, and a fourth pair of drivers, wherein respective drivers of the first, second, third, and fourth pairs of drivers are configured to output respective data patterns comprising at least three consecutive identical bits.
