RF and Baseband Signal Processing
applications are being embedded in different kinds of products to an
increasing extent - a development that has highlighted the need for
better RF design work. This lack of connectivity can be a major
problem, as the need for smaller and cheaper communication devices,
such as mobile phones, has increased the need to integrate RF and
digital electronics, both at the design level and in end-products.
In principle, the RF
design flow consists of three tasks: architecture design,
circuit-level design, and physical manufacturing. Circuit simulation
is essentially a support function, for verifying that a circuit
operates correctly prior to starting manufacturing.
