Abstract
A time-interleaved digital-to-analog converter for an optical transmitter includes a DAC core having a plurality of slices and current sources for converting complementary data signals to analog signals at output nodes of the DAC core, a down switch circuitry configured to connect, for each slice of the DAC core, a current from one of the current sources to a first data input path or a second data input path respectively corresponding to first complementary data signals and second complementary data signals supplied to the slice of the DAC core, an up switch circuitry configured to connect the current to the output nodes, and a data switch circuitry configured to, for each slice of the DAC core, selectively connect the current received via the down switch circuitry and either the first data input path or the second data input path.
