A recovery apparatus for solving a branch mis-prediction, and a method and a central processing unit thereof are provided. In the present invention, C is incorporated into the collector by epitaxy in a perimeter trench etched into the collector region to better control the carbon profile and location. By extracting a pitch from this signal component, the number of erroneous tuning operations can be reduced. The antenna is disposed over the band gap surface on the front side of the ground plane to be spaced away from the band gap surface.
