WebBinary DACs are used for the LSB elements because of their much smaller size when created with weighted transistors. This concept is nicely illustrated in a publication by Horsky4 for a monotonic 16-bit DAC designed for harsh environment sensor applications. Horsky utilized a seven-bit MSB unary current DAC followed by a five-bit binary current ... Web– Binary-weighted DAC – Unit-element (or thermometer-coded) DAC – Segmented DAC – Resistor-string, current-steering, charge-redistribution DACs • Oversampling DAC – Oversampling performed in digital domain (zero stuffing) – Digital noise shaping (ΣΔmodulator) – 1-bit DAC can be used – Analog reconstruction/smoothing filter
Webthat is, the resistors are binary weighted. Single-pole, double-throw switches are used, and each resistor that is not supplying current from the reference voltage V r is connected to ground. The switches of this converting circuit represent the binary digits (bits) a k in each position of a binary number. Counting from the left, the first switch represents the most …
