Abstract
A highly efficient, single sided circuit board layout design providing magnetic field self-cancellation and reduced parasitic inductance independent of board thickness. The low profile power loop extends through active and passive devices on the top layer of the circuit board, with vias connecting the power loop to a return path in an inner layer of the board. The magnetic effect of the portion of the power loop on the top layer is reduced by locating the inner layer return path directly underneath the power loop path on the top layer.
