Current-steering Digital-to-Analog Converters (DACs) are commonly the architecture of choice for analog signal synthesis from MHz to sub-THz frequencies in a variety of applications ranging from wireless and wired communication, instrumentation, imaging to defense among others. This tutorial will guide the audience from the basic architectural concepts and simplest circuit implementations to the different types of impairments and ways to mitigate them. Trade-offs, circuits and layout techniques to overcome them, and examples of actual high-speed DACs embodying the different concepts will be discussed in a intuitive fashion, providing the audience with selected literature references for deepening the material as needed.
