Abstract
The present invention provides a bar circuit for reducing cross talk and eddy current of an integrated circuit. The bar circuit comprises a semiconductor substrate with a first conductivity type; a strip of first well with a second conductivity type in the semiconductor substrate; and a strip of second well with the second conductivity type in the semiconductor substrate. The strip of second well is located below and adjacent to the strip of first well, whereby forms a junction barrier for reducing the cross talk and the eddy current.
