What is basic Analog Design?

Analog design is rather challenging than digital design as analog circuits are sensitive to noise, operating voltages, loading circumstances and other conditions that has severe effects onto performance. Still process technology poses exact topological restrictions onto the circuit. Analog designer has to deal along with real time continuous signals and whether manipulate them effectively even into harsh environment and into brutal operating circumstances.

Analog circuits usually deal along with instant value of voltage and current (real time). Can acquire any value into the domain of specifications for the device includes passive elements that contribute to the noise (thermal) of the circuit. They are generally more sensitive to external noise more so since for a particular function an analog design uses much less transistors providing design challenges over temperature ranges and process corners deals along with many of device level physics and the state of the transistor plays a extremely important task.
