Description
Technical field
The present invention relates to launching and receiving wireless communication signals, more particularly to upconverter with
The communication system of frequency converter.
Background technology
Due to deep-submicron (deep sub-micro) complementary metal oxide semiconductors (CMOS) (CMOS) technique
Propulsion, digital circuit becomes less and less, and power consumption is more and more lower.That is, the technique is flexible
Property (process scaling) allow more transistors to be realized in same region, or need one it is smaller
Region realize identical number of transistors.Therefore, in order that portable set (such as mobile phone) subtracts
Small size and extension battery life are, it is necessary to realize various circuits by deep-submicron CMOS process.For
Radio design aspect, it is also very desirable to be converted into more radio frequency (RF)/intensive radio components of simulation
Digital Dense type is designed, to make full use of the retractility of the technique.
In digital radio design aspect, because signal source has been digitized, therefore it is easier to realize number
Word transmitter portion, and uniquely to be considered be inband signaling generation.But, digit receiver part is
It is difficult to realize because signal source is simulation, and receiver part need to consider inband signaling and with it is outer it is dry/
Stopband.It is preferably integrated to generally mean that smaller device size and lower cost.But, if wirelessly
Electricity design is not efficiently converted into Design of digital to reduce the size of radio design, then for radio
Circuit it is integrated, it includes digit emitter part and digit receiver part, is produced into greatly increasing
This.For example, in more advanced semiconductor technology, transmitter portion and receiver section are integrated in same
It is not cost-effective design on wafer.
Accordingly, it would be desirable to a Communication System Design for innovation, its can by appropriate system partitioning and integrated,
Make equipment volume smaller, less expensive, and with lower current drain.
The content of the invention
The present invention provides a kind of communication system, including:One first wafer, including a upconverter and a digital base
Tape handling circuit;One second wafer, and first wafer separate, and including a low-converter;And one
Front-end circuit, for an antenna to be couple into first wafer and second wafer.
A kind of communication system is provided, including:One first wafer, for performing digital base band processor, Yi Jigen
One first signal is produced according to a secondary signal, wherein the secondary signal comes from the digital base band processor
An output signal, and first signal frequency higher than the secondary signal frequency;One second wafer,
With first wafer separate, and for according to one the 4th signal produce one the 3rd signal, wherein the described 4th
Frequency of the frequency of signal higher than the 3rd signal;And a front-end circuit, for by first signal
An antenna is couple to from first wafer, and the 4th signal is couple to described from the antenna
Two wafers.
Communication system proposed by the present invention, by rational schedule system subregion and integrated, for example will be different
Functional module is arranged on different wafers such that it is able to use the digitized advantage of transmitter so that described
Communication system is more cost effective and energy-efficient.
