Abstract :
This paper describes the design and implementation of a upconverting D/A converter (DAC). Designed converter is capable of upconverting two 12-bit 60 MHz (in-phase and quadrature) signal bands around 2.4 GHz radio frequency. Upconversion is implemented by reorganizing switching scheme of a traditional current-steering D/A converter. Designed with 0.13 mum CMOS process, total area and estimated power consumption including DSP are 8.14 mm2 and 520 mW respectively.
