Analog System Architecture
Analog system architecture addresses the fundamental challenge of designing complex analog systems where multiple subsystems must work together cohesively while maintaining the precision and signal integrity that analog circuits demand. Unlike digital systems where noise margins provide tolerance for imperfections, analog systems require careful attention to every aspect of the physical implementation, from how reference voltages are distributed to how clock signals reach their destinations without accumulating jitter or noise.
At the system level, analog design extends beyond individual circuit blocks to encompass the infrastructure that connects them. Power distribution networks must deliver clean, stable supplies without introducing crosstalk between sensitive circuits. Grounding architectures must manage return currents to minimize interference. Clock and reference distribution systems must maintain timing accuracy and voltage precision across entire boards or systems. Signal routing must preserve bandwidth and minimize coupling. These system-level concerns often determine whether a theoretically excellent circuit design achieves its potential in practice.
