摘要： Disclosed herein is a differential amplifier using body-source cross coupling. In a common gate differential amplifier in which common gate amplifiers are implemented in a differential structure, since the bodies of the common gate amplifiers are cross coupled to the sources of the opposite common gate amplifiers, it is possible to increase transconductance due to body effect to improve a gain. Since the potential of the body is equal to that of the source in a DC mode, a breakdown voltage reduction problem is alleviated.

摘要： A method for manufacturing a chip scale package comprises preparing a tape wiring board that includes a polyimide tape having top and bottom surfaces, Cu traces formed on the bottom surface of the tape, a window formed in the tape to enable the Cu traces to be connected to a semiconductor chip attached below the board, multiple connection holes formed in the tape to expose portions of the Cu traces therethrough and define solder ball mounting pads, and an elastomer chip carrier attached to the bottom surface of the tape. The method includes applying either a pre-flux or a cover sheet over the solder ball mounting pads. The pre-flux and the cover sheet each prevents the solder ball mounting pads being plated with gold. This, in turn, prevents the formation of intermetallic compounds in the solder balls so that the bond strength between the solder balls and a pad to which they attach is improved.

摘要： A voltage regulator includes an active control switch, an active sync switch, a driver circuit, and a gate resistor. The active control switch is coupled between an input voltage line and an input of an energy storage device. The active sync switch is coupled to the input of the energy storage device. The driver circuit is coupled to the control and sync switches to alternately drive each of the control and sync switches into a conducting state to produce a regulated voltage at an output of the energy storage device. The gate resistor is coupled in series within a control path of the sync switch. The gate resistor has a resistance value that is tuned to reduce an anticipated dead time between a turn-off time of the sync switch and a turn-on time of the control switch.
