Description
Summary:Recent wideband data converters [1-4], capable of direct digitization and sampling of C-band RF signals with moderate power consumption, provide an attractive architectural option for muiti-band software-defined-radio RF transceivers used in wireless infrastructure radio units. In these applications, system integration is critically important and requires the data converters to be integrated together with the digitallow-phy layer of the radio unit. This, in turn, determines the selection of the process technology. Power consumption is also very important since keeping the junction temperature down can be very challenging in integrated systems with limited heat dissipation inherent to small form factors and increasingly compact systems. A 14b 16GS/s DAC with high linearity and low power dissipation, which is intended for such demanding applications is here presented.
