Abstract :
This paper presents the design of an area-power efficient digital down-converter suitable for broadband communication systems. The DVB-S standard has been used as a design example. It has been shown that by selecting a bandpass sampling to generate only one spectral image, the case in which the relationship between the digital carrier frequency and the sampling frequency is 1/4, not only gives the smallest area but the lowest power consumption.
