Designing of a digital to analog convertor fully in CMOS ,0.18μm ,1.8V technology with SFDR more than 70dB

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. We can compound different methods of designing different parts of digital to analog converters to achieve to complex designing. complex designings are very common methods in converters designing because compound different methods points. In this article we design and simulate a digital to analog converter .This 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
