Abstract: A redundancy passgate circuit is implemented in NMOS technology in order to provide a more rapid transmission of the transmitted signals. The circuit provides for the more rapid signal transmission by reducing the capacitance experienced by the input signals. The reduced capacitance loading is achieved at the expense of a greater layout area and a requirement for an on-chip power supply.

Abstract: A hybrid leadframe-over-chip (LOC) semiconductor package is generally comprised of bonding finger elements located over a surface of a semiconductor component and electrically coupled, by means of conducting wires, to the bonding pads located on the surface. In addition, at least one bonding finger is located outside the boundary of the surface of the semiconductor component. Each bonding finger located outside the boundary is coupled, by a conducting wire, to a bonding pad positioned within the boundary of the semiconductor component. In this manner, for a given semiconductor component size and for given routing and lead dimension constraints, a larger number of conducting paths can be provided between the leadframe and the semiconductor component.

Abstract: An all electronic tuning system is described for establishing a frequency of a local oscillator in a television receiver. When a channel selection is made, a number representing the desired channel is entered in a memory circuit. A first plurality of frequencies is generated in response to a channel selection, and a VCO employed as a local oscillator is caused to increase in frequency. When the VCO frequency differs from the first plurality of frequencies by a predetermined amount, a second plurality of frequencies is generated. Each frequency generated in said second plurality of frequencies is compared with said VCO frequency. When a predetermined difference exists between said VCO frequency and said second plurality of frequencies, a count is recorded. When the recorded count is equivalent to the number obtained in the memory circuit, the VCO tuning is inhibited and the VCO frequency is stabilized until a subsequent channel selection is made.
