ABSTRACT: This paper reports the design and simulation of an optimized 6-bit 1-MSB and 2-MSB Partial Binary Tree Network (PBTN) Dynamic Element Matching (DEM) current steering Digital-to-Analog (DAC). Then, the work of the 6-bit design is extended to implement an 8-bit DAC both for 1-MSB and 2-MSB respectively. From the simulation, results show that for 6-bit 1-MSB DAC, Differential Non-Linearity(DNL) of 0.00001895 LSB,Integral Non-Linearity(INL) of 0.0001457 LSB and power consumption of 2.806 mW (excluding load) are obtained. Meanwhile, for 6-bit 2-MSB DAC, DNL of -0.00928 LSB, INL of 0.008669 LSB and power consumption of 2.8mW (excluding load).....
