    Trenches etched in silicon, for use in isolation, capacitors, or as device locations, require a profile with smooth, straight (non-bowed) sidewalls and rounded bottoms. The smooth walls are necessary to ensure oxide integrity, straight walls allow refilling without voids, and rounded bottoms prevent slipplane...

    Most applications for lossless current sensing involve detection of overcurrent conditions in power switching cir- cuits. Current-sensing MOSFETs contain two current sensing terminals (MIRROR and KELVIN) in addition to the DRAIN, SOURCE and GATE terminals. A voltage which is linearly proportional to the drain current...

    Time stamping is quickly becoming a standard feature on all new pagers, however, it has been limited to "display" type pagers. Other pagers, particularly, "stored voice" type pagers, currently lack a feasible time stamping feature. There are conventional methods that could be used to provide time stamping for these...

    This invention resolves the problem of having insufficient display area for viewing long alphanumeric messages in pagers Because of their compact displays, alphanumeric pagers typically permit only partial viewing of long messages. By incorporating a pager into a handheld television, the user will be able to receive...

    In a typical microcomputer reset circuit, one or more of the microcomputer's outputs are monitored to determine if a hardware reset should be invoked, and if so, to generate repetitive resets until normal microcomputer output is detected. A typical reset circuit (FIG. 1) employs a comparator circuit with hysteresis...
