An electrical device is disclosed, comprising electrical components forming an electrical circuit, with a trim circuit comprising two or more trim cells providing selectively removable resistances between first and second nodes in the electrical circuit. The resistance between the nodes is trimmed incrementally by application of trim signals to a single pair of terminals or pads on the device, allowing post-packaging trimming. Methods are also disclosed for selective removal of resistance between first and second nodes in a packaged electrical device.
Methods And Apparatus For Trimming Electrical Devices
Trimming methods and apparatus are disclosed for selectively removing resistance between first and second nodes in an electrical device, including trim circuits comprising a resistor and a diode formed in the resistor body having a conductive portion which may be selectively melted to short the resistor. A multi-bit trim cell is disclosed having trim cells individually comprising a resistor with a diode formed in the resistor body for selectively shorting the resistor, and a fuse for selectively disconnecting the diode from a trim pad.

Abstract:
One embodiment of the invention includes a power regulation system. The system comprises a power regulator configured to periodically generate a switch signal that regulates a current flow through an inductor to set a magnitude of an output voltage. The system further comprises an overvoltage protection circuit configured to monitor a peak voltage magnitude of the switch signal and to generate an overvoltage indication signal in response to the peak voltage magnitude of the switch signal exceeding a predetermined limit.
Stem Cells Modified To Facilitate Threonine Catabolism
A BS determines an amount of resource overloading for a contention transmission unit (CTU) access region associated with a grant-free uplink transmission scheme in a multiple access system. The BS determines a modulation and coding scheme (MCS) limit indicating a maximum MCS level for the CTU access region. The BS sends the MCS limit to a plurality of user equipments (UEs) associated with the first CTU access region. A UE receives from the base station the MCS limit and determines a first MCS index within the MCS limit for a first uplink transmission. The UE sends the first uplink transmission to the base station using a CTU in the CTU access region. The first uplink transmission includes user data and the first MCS index determined at the first UE.
