Why Analog ?
 Processing of natural signals
 Digital communication
Attenuation and distortion of data
through a lossy cable.(long & speed)
Use of multi-level(4) signaling to
reduce the required bandwidth (half).

Why is analog design difficult?
 Whereas digital circuits entail primarily one trade-off between speed and power
dissipation, analog design must deal with a multi-dimensional trade-off consisting
of speed, power dissipation, gain, precision, supply voltage, etc.
 With the speed and precision required in processing analog signals, analog
circuits are much more sensitive to noise, crosstalk, and other interferers than
are digital circuits.
 Second-order effects in devices influence the performance of analog circuits
much more heavily than that of digital circuits.
 The design of high-performance analog circuits can rarely be automated, usually
requiring that every device be “hand-crafted.”
 Despite tremendous progress, modeling and simulation of many effects in analog
circuits continue to pose difficulties, forcing the designers to draw upon
experience and intuition when analyzing the results of a simulation.
 Developed and characterized for digital applications, such technologies do not
easily lend themselves to analog design, requiring novel circuits and
architectures to achieve a high performance.
