Why do an ASIC?
Well, why not?I Costly (development, design iteration time, production)I Inflexible and low level of reusability
So why bother?I Ultimate performance (speed, power)I Ultimate miniaturizationI Reliability (fewer points of failure)I Very cheap for high volume production (e.g. CPUs)I For (Mixed-Signal) Systems-on-Chip (SoC)

Why do a Digital ASIC?
See previous arguments for and against ASICThe most important is the small price per piece for high volumeproduction particularly for large scale systems-on-chip (SoC), e.g.CPU, but also FPGAs, GPUs, Microcontrollers etc. (mostly not ’fullcustom’ design but automated ’synthesis’), but real understandingon a single transistor level is required for the ultimate performancein speed, miniaturization, power consumption. Analogous in SW ofwhere it’s worth to program in Assembler.

Even Computers are Analog ;-)
Where the digital abstraction breaks down
• Gates• Increasing speed
– Why this degradation?– How do we improve
performance?– Digital → analog
• Going for speed…
• Noise/interference
– Where does this noise originate?– How do we reduce this noise/interference?– Digital → analog
• When scaling down size and scaling up complexityTSL inf3410

Amplifiers: importance
I What a switch is for digital electronics, amplifiers are foranalog electronics:
I the most important active element. (A switch is an amplifier.)I an abstraction/simplification of a physical device.
I An amplifier is required where-ever electronics (or a biologicalorganism) interfaces with the real world, mediating betweensensors and actuators and processing circuitry. (The world isanalog.)
I Maintaining signal energy in processing requires amplification.

Amplifiers: definition
An amplifier is a device that linearly/monotonically projects aninput signal range to an output signal range, increasing power(usually) and optionally changing the signal representation(transducer).
