Abstract: An integrated circuit (IC) including a plurality of finfet cells designed with digital circuit design rules to provide smaller finfet cells with decreased cell heights, and analog circuit cell structures including first finfet cells of the plurality of finfet cells and including at least one cut metal layer. The smaller finfet cells with decreased cell heights provide a first shorter metal track in one direction and the at least one cut metal layer provides a second shorter metal track in another direction to increase maximum electromigration currents in the integrated circuit.

Abstract: A control circuit for the switching regulator and a method for regulating electrical signal are disclosed. The control circuit for the switching regulator includes a switching regulator and a clock control unit. The switching regulator regulates an output voltage according to a reference voltage and a feedback voltage. The clock control unit is coupled to the switching regulator, and the clock control unit includes an oscillator and a pulse blanking modulator. The oscillator provides an oscillation signal, and the pulse blanking modulator is configured to generate a control signal that blanks a portion of the oscillation signal. The clock control unit provides the control signal in order to maintain an output electrical signal in a sleep mode of the switching regulator within a predetermined range.

Abstract: A headphone is disclosed, which comprises: a first earpiece, formed with a first receiving groove and a first frame in a manner that the first frame is designed to be received inside the first receiving groove; a second earpiece, formed with a second receiving groove and a second frame in a manner that the second frame is designed to be received inside the second receiving groove; and a coupling unit, mounted respectively to a free end of the first frame and a free end of the second frame. In an embodiment, the first frame, the second frame as well as the coupling unit attached thereto can be received inside the first earpiece and the second earpiece in respective, by that the size of the headphone can be reduced for easy depository and carriage.
