Abstract :
The paper investigates and compares two different solutions to improve a printed circuit board designed for a portable computer main board. The issue represents the analog circuits and switching power supplies. The main example is a simple analog circuit, low dropout regulator (LDO), integrated into a complex analog circuit. The LDO stability versus the printed circuit board (PCB) design rules represents today a real challenge for electrical engineers and PCB designers.
