A polishing pad, comprising a mounting surface and an opposing polishing surface with a polishing pattern having at least one aperture thereon, is formed with an adhesive layer adhered to the mounting surface with uniform adhesive strength therebetween. The system preferably interfaces to the Full Authority Digital Engine ControllerEngine Control Unit and can record hundreds of engine parameters with a preferred sampling frequency of about one second. The discharge structure includes an opaque insulative substrate, with a plurality of addressing electrodes, an opaque dielectric layer, a plurality of separation walls, and a fluorescent layer formed at each of opposite surfaces thereof. An auxiliary MOSFET current mirror device with the body connected to ground may be added in parallel with the body-biased current mirror device to eliminate a non-monotonicity of the current output.
