Description

Communication system

Technical field

The present invention relates to emitting and receiving wireless communication signals, more particularly to upconverter and low-converter Communication system.

Background technology

Due to the propulsion of deep-submicron (deep sub-micro) complementary metal oxide semiconductor (CMOS) technique, number Circuit becomes less and less, and power consumption is lower and lower.That is, the retractility (process scaling) of the technique permits Perhaps more transistors are realized in same region or a smaller region are needed to realize identical number of transistors. Therefore, it in order to which portable device (such as mobile phone) is made to reduce size and extends battery life, needs to pass through deep-submicron CMOS Technique realizes various circuits.For radio design aspect, it is also very desirable to by radio frequency (RF)/intensive radio components of simulation More digital Dense type designs are converted into, to make full use of the retractility of the technique.

In digital radio design aspect, since signal source has been digitized, it is easier to realize digital transmission Device part, and uniquely to be considered be inband signaling generation.But digit receiver part is difficult to realize, because of letter Number source is simulation, and receiver part needs to consider inband signaling and with outer dry/stopband.It is preferably integrated to generally mean that more Small device size and lower cost.But if radio design is not efficiently converted into Design of digital to reduce The size of radio design, then for the integrated of radio circuit, including digit emitter part and digit receiver part, Production cost will be greatly increased.For example, in more advanced semiconductor technology, transmitter portion and receiver section are integrated It is not cost-effective design on same wafer.

Therefore, it is necessary to the Communication System Designs of an innovation, by appropriate system partitioning and can integrate, make equipment It is volume smaller, less expensive, and with lower current drain.

Invention content

The present invention provides a kind of communication system, including：One first wafer, including a upconverter and a digital base band processor Circuit；One second wafer, and first wafer separate, and including a low-converter；And a front-end circuit, for by one day Line is couple to first wafer and second wafer.

A kind of communication system is provided, including：One first wafer, for performing digital base band processor and according to one second Signal generates one first signal, wherein the second signal comes from an output signal of the digital base band processor, and institute The frequency for stating the first signal is higher than the frequency of the second signal；One second wafer, and first wafer separate, and for root A third signal is generated according to a fourth signal, wherein the frequency of the fourth signal is higher than the frequency of the third signal；And One front-end circuit, for by first signal from first wafer be couple to an antenna and by the fourth signal from The antenna is couple to second wafer.

Communication system proposed by the present invention, by rational schedule system subregion and integrated, such as by different function moulds Block is arranged on different wafers, so as to use the digitized advantage of transmitter so that the communication system has more cost Benefit and energy-efficient.
