WebThe R-2R DAC is one of the most common types of Binary-Weighted DACs. It consists of a parallel binary-weighted resistor bank. Each digital level is converted to an equivalent analog signal by the resistor bank. The input/output transfer curve of the binary weighted DAC can be nonmonotonic, which means that the transfer curve can reverse its ... WebMay 1, 2024 · Its application in the field of signal processing and wireless communication demands high speed and high resolution. A Current steering DAC serves the purpose of achieving higher bandwidth and sampling rate [1]. On the architecture level, it is categorized into unary, binary, and segmented architectures.
