摘要： A negative feedback system includes a first summation module for receiving a system input and outputting a first summation output. A first forward module is coupled to the first summation module for receiving the first summation output and outputting a first forward output. A feedback module is coupled to the first summation module for receiving the first forward output and outputting a feedback output to the first summation module, wherein the first summation output equals the system input minus the feedback output. An error compensation module, having a compensation gain, is coupled to the first summation module for receiving the first summation output and outputting an error compensation output. The compensation gain is adjusted to provide the error compensation output with a predetermined value, such that an output error of a system output is substantially eliminated by combining the error compensation output with the first forward output.

摘要： A differential amplifier without common feedback is disclosed. The amplifier has a low gain fully differential amplifier and a high gain fully differential amplifier connected in parallel with the low gain fully differential amplifier. When first and second inputs feed into the low and high gain fully differential amplifiers, the low gain fully differential amplifier is used to bias the high gain fully differential amplifier so that a first and second voltage output generated by the high gain fully differential amplifier is stable during a common mode operation without being impacted by fluctuation of the inputs.

摘要： Among other things, one or more techniques for graded dummy insertion and a resulting array are provided herein. For example an array is a metal oxide semiconductor (MOS) array, a metal oxide metal (MOM) array, or a resistor array. In some embodiments, a first region and a second region are identified based on a density gradient between a first pattern density associated with the first region and a second pattern density associated with the second region. For example, the first pattern density and the second pattern density are gate densities and/or poly densities. To this end, a dummy region is inserted between the first region and the second region, the dummy region includes a graded pattern density based on a first adjacent pattern density and a second adjacent pattern density. In this manner, graded dummy insertion is provided, thus enhancing edge cell performance for an array, for example.

摘要： A cover latching mechanism (100) used in a portable electronic device is described including a latching base (20), a cover member (10), and a latching member (30). The cover member has a latching protrusion (14) arranged thereon. The latching member is used to latch the cover member to the latching base and defines a latch space (338) and a release space (337). The cover member can be latched to the latching base by a movement of the latching protrusion from the release space into the latch space, and then be released from the latching base by an opposite movement of the latching protrusion from the latch space into the release space, the two movements being caused by pushing or pulling the cover member along the latching base.
