Abstract: The present disclosure relates to an integrated chip. The integrated chip includes a substrate having one or more interior surfaces forming a recess within an upper surface of the substrate. Source/drain regions are disposed within the substrate on opposing sides of the recess. A first gate dielectric is arranged along the one or more interior surfaces forming the recess, and a second gate dielectric is arranged on the first gate dielectric and within the recess. A gate electrode is disposed on the second gate dielectric. The second gate dielectric includes one or more protrusions that extend outward from a recessed upper surface of the second gate dielectric and that are arranged along opposing sides of the second gate dielectric.

Abstract: A real-time sampling device for being coupled to a processing unit includes a first register, a second register, a third register, a trigger output element and a timer for outputting an interrupt signal. The first register externally receives and processes a first input signal to produce processed data. The second register retrieves the processed data from the first register upon receiving the interrupt signal, and the processing unit, upon receiving the interrupt signal, retrieves the processed data from the second register and performs calculation thereon to produce a processed data calculation value and temporarily store the processed data calculation value in the third register. The trigger output element outputs the processed data calculation value in the third register in real time upon receiving the interrupt signal. The real-time sampling device an be applied to digital control systems in order to perform real-time sampling on controlled subjects.

Abstract: A motion control servo loop apparatus, comprising: a feed-forward control module, and a proportional-integral-derivative (PID) control loop and a compensation adder. The feed-forward control module is capable of generating a feed-forward compensation. The PID control loop further comprises: a proportional control module, an integral control module and a derivative control module. The proportional control module is capable of generating a proportional compensation. The derivative control module is capable of generating a derivative compensation. The integral control module uses a digital differential analyzer (DDA) algorithm to perform integration for accumulated errors with respect to each sampling clock at each DDA pulse and thus output an accumulated error, which is then processed to generate an integral compensation.
