A first functional block (101) is coupled to the first power supply line (110) via a first conductive path including a first switch (131) and a second functional block (102) is coupled to the first power supply line (110) via a second conductive path including a second switch (132), the first switch (131) and the second switch (132) being arranged to respectively disconnect the first functional block (101) and the second functional block (102) from the first power supply line (110) for switching said functional blocks (101, 102) from an active mode to a standby mode.

摘要： An integrated circuit (300) has a regular grid formed by substantially identical building blocks (100a-i). To avoid possible routing conflicts around the edges of the integrated circuit (300), which can be introduced by the use of a single type of an asymmetric building block, the integrated circuit (300) is extended with routing cells (200) that provide routing at the edges of the grid that are uncovered by the routing networks of the building blocks (100a-i). The routing cells (200) and the switch cell (250) are combined with a first routing structure (330) and a second routing structure (340) to form a routing network (280) surrounding the grid of the integrated circuit (300). Consequently, an integrated circuit (300) is presented that comprises only a single type of building block (100a-i) but still has a fully symmetric routing architecture.

摘要： A flash analog-to-digital converter comprises a resistive string powered by a reference voltage source for providing a set of equidistant reference voltages and a set of comparators for comparing the analog input signal with the reference voltages. A set of switches are arranged and controlled to perform an algorithm for mitigating the influence of mismatches between the components. The switches are arranged between the reference voltage source and the resistive string so that switches in the reference inputs to the comparators are avoided. The resistive string is preferably circular. The converter can handle differential signals.

摘要： As technology scales, on-chip interconnects are becoming narrower, and the height of such interconnects is not scaling linearly with the width. This leads to an increase of coupling capacitance with neighboring wires, leading to higher crosstalk. It also leads to poor performance due to poor RC response at the receiving of the wire, which may even result in failure in very noisy environments. An adaptive threshold scheme is proposed in which receiver switching thresholds are adjusted according to the detected noise in bus lines. These noise levels are dependent on both the front-end processing (transistor performance) as well as on the backend processing (metal resistance, capacitance, width and spacing). The circuit therefore automatically compensates for process variations.

摘要： Embodiments of the invention are related to sense amplifiers. In an embodiment involving a sense amplifier used with a memory cell, signals BL, ZBL, SN and SP are pre-charged and equalized to a voltage reference, e.g., Vref, using an equalizing signal. A compensation signal, e.g., SAC, is applied to compensate for the mismatch between transistors in the sense amplifier. The word line WL is activated to connect the memory cell to a bit line, e.g., bit line ZBL. Because the memory cell shares the charge with the connected bit line ZBL, it causes a differential signal to be developed between bit lines BL and ZBL. When enough split between bit lines BL and ZBL is developed, signals SP and SAE are raised to VDD (while signal SN has been lowered to VSS) to turn on the sense amplifier and allow it to function as desire. Other embodiments and exemplary applications are also disclosed.
