摘要： A method performed by a computer system includes: searching leakage current values of associated with cell abutment cases which are associated with terminal types of abutted cells of a semiconductor device; determining leakage probabilities according to the cell abutment cases; calculating expected boundary leakages between the abutted cells based on the leakage probabilities and the leakage current values; and generating a layout of the semiconductor device according to the expected boundary leakages. Two of the leakage probabilities correspond to two of the cell abutment cases, respectively, and the two of the leakage probabilities are different from each other when the two of the cell abutment cases are different from each other.

摘要： Envelope tracking systems with modeling for power amplifier supply voltage filtering are provided herein. In certain embodiments, an envelope tracking system includes a supply voltage filter, a power amplifier that receives a power amplifier supply voltage through the supply voltage filter, and an envelope tracker that generates the power amplifier supply voltage. The power amplifier provides amplification to a radio frequency (RF) signal that is generated based on digital signal data, and the envelope tracker generates the power amplifier supply voltage based on an envelope signal corresponding to an envelope of the RF signal. The envelope tracking system further includes digital modeling circuitry that models the supply voltage filter and operates to digitally compensate the digital signal data for effects of the supply voltage filter, such as distortion.

摘要： An apparatus and method for determining speech privacy can include deriving a room adjacency matrix based on a building design, model, or floor layout. Using class values or other values representing a degree of sound transmission or attenuation through the walls and ceilings a sound level (e.g., measured in decibels) of speech transmitted from one room to the next can be compared to the background noise levels. Speech privacy can be provided when the transmitted speech between adjacent rooms is less than the background noise. Choices of wall and/or ceiling construction and materials may be modified when the determined speech privacy fails to satisfy the target values. In a building information modeling (BIM) application, the class values for ceilings and walls can be automated based on attributes defined for wall and ceiling objects defined within the BIM application.
