dc.description.abstract-translatedThis paper presents the design of an 11-bit dual D/A converter for the transmission of I-Q encoded information. The intended field of application is the automotive industry. Therefore the specific environmental hazards had to be considered, primarily the wide operating temperature range. The design is in the ON Semiconductor smart power 350 nm CMOS technology. The main function of the converter is to transmit information encoded into I-Q signal representation. The I and Q signal paths are in reality represented with sine and cosine signals. In addition, this information can have the maximum change rate of 3000 rps. The decomposition of transmitted information is expected to occur at the receiver side in the I-Q decoder block. To comply with these requirements the D/A converter has to be dual (sine and cosine), bipolar and of a segmented current-steering architecture (best accuracy/area tradeoff). Goals have been respectively selected to have DNL < ± 0.5 LSB (to guarantee monotonicity) and INL < ± 3 LSB in order to achieve acceptable linearity. Channel gain mismatch has to be better than 1 % to fulfill the dual channel accuracy requirement, calculated from the sensitivity of the output error on the signal amplitude mismatch. Special attention has been paid to the layout placement of the current steering matrix elements and to the switching strategy as well. The article provides design overview with the measurement results of the manufactured prototype.en
