  • Publication number: 20170194421
    Abstract: An integrated circuit device having a body bias voltage mechanism. The integrated circuit comprises a resistive structure disposed therein for selectively coupling either a body bias voltage or a power supply voltage to biasing wells. A first pad for coupling with a first externally disposed pin can optionally be provided. The first pad is for receiving an externally applied body bias voltage. Circuitry for producing a body bias voltage can be coupled to the first pad for coupling a body bias voltage to a plurality of biasing wells disposed on the integrated circuit device. If a body bias voltage is not provided, the resistive structure automatically couples a power supply voltage to the biasing wells. The power supply voltage may be obtained internally to the integrated circuit.

  • Patent number: 8350616
    Abstract: A drive frequency source with two selectable output frequencies connected to two charge pump arrays. A first array of basic charge pump units is connected to the first output frequency and a second array of basic charge pump units is connected to the output frequency. One or more of the basic charge pump units making up the aforementioned first and second charge pump arrays has an enable input allowing its output current contribution to be added or subtracted from the total array output. The output of the first array is coupled to a P-type substrate and the output of the second array is coupled to an N-well residing in the P-type substrate. A controller may be coupled to the drive frequency source for selecting the output frequencies, and an output monitor may be coupled between the array outputs and the controller to provide feedback.

  • Patent number: 8085084
    Abstract: An integrated circuit with body-bias inputs coordinated by a switch at initial power application. A switch coupled to the N-well bias and P-type substrate bias lines of an integrated circuit selectively couples the substrate to ground or the substrate bias supply, depending upon the state of the bias supply lines. During power-up and the initial application of the N-well bias, the substrate is coupled to ground to prevent a leakage induce rise in the substrate potential. Upon sensing the presence of the substrate bias potential on the substrate bias line, the switch couples the substrate to the substrate bias line instead of ground. In another embodiment, a switch indirectly senses the availability of the substrate bias potential by sensing a charge pump enable signal.

  • Patent number: 7722827
    Abstract: A fast light off flow-through ceramic substrate is provided that is particularly adapted for use as a catalytic converter. The substrate is formed from a body of ceramic material having axially opposing inlet and outlet ends for receiving and expelling the flow of automotive exhaust gas, respectively. The body contains a network of walls coated with a catalyst that define axially-oriented flow-through cell channels. The average thermal mass (ATM1) of a first axial region of the walls adjacent to the inlet end is at least 20% less than the average thermal mass (ATMTOT) of all of the walls. The lower average thermal mass of the walls in the first region advantageously shortens the light off time for the catalyst within the substrate to effectively neutralize automotive pollutants. The reduction of the average thermal mass in only the first axial region of the walls advantageously maintains the strength of the resulting body of ceramic material, and further increases the cool down time of the body.
