Some of these differences are highlighted below. Digital circuits are nonlinear, analog circuits are mostly linear. Analog circuits are much more sensitive to noise and disturbance compared to digital circuits. Digital circuits are generally more noisy than analog circuits. Analog circuits may require less chip area and power for certain applications.
Digital circuits can operate at a much lower supply voltage, which is desirable.
An interface is needed between the analog and digital domain. Our research includes the items below. Design of single-chip solutions including both analog and digital circuits. Our method does not suffer from this. One of the new ideas seems very promising.
