Designing of a Digital to Analog Convertor Fully in CMOS, 0.18μm, 1.8V Technology with SFDR more than 70dB

摘要

Background/Objectives: Nowadays in new system of communication, analog to digital and digital to analog converters are used plenteously. Digital to analog converters are converters that receive digital data and convert it to an analog signal. Methods/Statistical Analysis: In this study a digital to analog converter has been fully designed in CMOS, 0.18μm, 1.8V technology. Findings: Designed converter receive 6 low-worth first bits in the form of binary and 4 worthy last bits in the form of unary thermometer codes. Output of this converter is in the form of sinusoidal signal. This converter has high amounts of SNR and SFDR. Application: In conclusion, this study illustrated that different methods of designing can be compounded to achieve to complex designing with better performance.
