The Art Of Analog Layout By Alan Hastings Portable ((better))

Start layout by placing the input differential pair and current mirror first. Everything else goes around them.

A powerful portable concept is the “dummy” device—a non-functional transistor or resistor placed at the ends of arrays to ensure every functional device experiences identical photolithographic and etching conditions. Similarly, common-centroid layouts for resistors (using unit elements arranged in a cross-coupled pattern) cancel linear and some quadratic process gradients. The art is recognizing that in analog, geometry is function. the art of analog layout by alan hastings portable

If you are a serious analog designer, buy the hardcover to support the legacy. But scan it, buy the official eBook, or find a high-quality PDF—do whatever you need to do to make this book portable. Because in the analog world, a reference you can’t reach is as useless as a transistor with no gate voltage. Start layout by placing the input differential pair
