The Art Of Analog Layout By Alan Hastings Portable Jun 2026

: Uses device cross-sections and physics to explain how layout geometries directly impact silicon performance.

The portable takeaway is the principle of common centroid geometry. By interdigitating or arranging devices symmetrically around a central point, any linear gradient in temperature, oxide thickness, or doping concentration across the wafer cancels out. Furthermore, Hastings emphasizes the importance of dummy structures at array edges to ensure identical etching and polishing environments. The mantra is simple: treat each matched pair as a single, distributed device, not two separate ones. the art of analog layout by alan hastings portable

Start layout by placing the input differential pair and current mirror first. Everything else goes around them. : Uses device cross-sections and physics to explain

Searching for is not about piracy or laziness. It is about workflow integration. It is about moving the world’s best reference text from the dusty bookshelf to the CAD terminal. Everything else goes around them

To create optimal analog layouts, designers should follow best practices, including:
