How can the shown folding structure reduces the gate resistance by factor of 4 .... i think it reduces it by factor 2 only ?
as it is written above this picture " We note that Folding reduces the gate resistance by a factor of four "

1st Case Resistors are in serires so effective R = R+R+R+R = 4R
2nd Case two pair resistors are in series which is in parallel to each-other so effective R = 2R parallel to 2R => 2Rx2R/(2R+2R) = 4RXR/4R =R
