  • Publication number: 20210366875
    Abstract: A semiconductor device includes a vertical column of wire bonds on substrate contact fingers of the device. Semiconductor dies are mounted on a substrate, and electrically coupled to the substrate such that groups of semiconductor dies may have bond wires extending to the same contact finger on the substrate. By bonding those wires to the contact finger in a vertical column, as opposed to separate, side-by-side wire bonds on the contact finger, an area of the contact finger may be reduced.

  • Patent number: 8791682
    Abstract: An apparatus includes a pass element comprising an input, an output and a control input.

A differential amplifier includes a non-inverting input coupled to the input, an inverting input coupled to the output, an amplifier output coupled to the control input and a bias current connection. The differential amplifier, with a bias current supplied, supplies the first signal along with a closed feedback loop from the output and supplies the second signal in absence of the bias current. A current source is coupled to the bias current connection and an enable input. The current source supplies the bias current and, in absence of an enable signal, disables the bias current.

  • Patent number: 8587972
    Abstract: An apparatus and a system include a multiplier circuit for receiving a sensed voltage and current of a of a load resistance coupled to a rectified voltage from a transformer's output whose input is from a DC-to-AC converter being supplied from a DC power generator having an internal resistance. The multiplier outputs a product of the sensed voltage and current. A differentiator circuit outputs a rate of change of the product. An integrator circuit outputs an integrated voltage indicating an accumulative rate of change of the product. A voltage-to-frequency converter circuit generates a voltage waveform having a frequency determined by the integrated voltage. A driver circuit uses the voltage waveform to output a control signal for controlling a frequency of the DC-to-AC power converter where the apparatus substantially matches an input resistance of the transformer to the internal resistance, thereby maximizing power transfer to the load resistance.

  • Patent number: 8384356
    Abstract: A self-contained power source to charge a battery and/or power a load is provided. The power source does not utilize a connection to an external power supply, such as AC mains and/or an AC to DC converter. In one embodiment, the self-contained power source includes an ultra low voltage power generator, such as 0.3V of a single solar cell, or even lower to slightly above the GND potential, that provides a voltage to a rechargeable battery, a load or both. A voltage converter with boost topology is used to supply a voltage comparable to the voltage of the rechargeable battery. A first push circuit containing a zero threshold voltage switch, a MUX circuit and a one-pulse-control block is utilized to ensure initial and continued operation of the voltage converter.
