Patents by Inventor Harish Raghavan

Harish Raghavan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200218304
    Abstract: Systems, methods, and apparatus for practical realization of a current source with a programmable temperature profile are described. The temperature profile can include profile segments with different programmable slopes. Programmable slopes of any one of the profile segments can be according to any of a ZTAT, PTAT and CTAT profiles. When integrated in an electronic device, the programmable temperature profile can be used statically with a pre-programmed configuration and optionally fused profile, or dynamically to control a performance of the electronic device via adjustments of the temperature profile.

  • Patent number: 10033333
    Abstract: Various methods and circuital arrangements for controlling an RF amplifier while reducing size, cost and power consumption are presented. Included is an amplifier controller unit that provides different current amplification stages, via corresponding calibration and control blocks, that can be used for calibrating an output power of the RF amplifier based on a reference current. Order of the current amplification stages starting from the reference current allow reduction in size, cost and power consumption. A fixed or programmable offset current may be added to an output current provided by a current amplification stage.

  • Patent number: 8390493
    Abstract: A voltage reference circuit provides a precision voltage reference output without requiring a filter capacitor. The voltage reference output is generated by a digitally-controlled source, which has a value set by the output of a digital filter that filters the output of a comparison circuit that compares the voltage reference output to another reference. A selectable mode can be provided to provide a fast response during a startup/reset period and an optional hold or narrowband response after startup. The mode selection may also offer selection of an externally-supplied digital control value and/or a resistor divider type voltage reference as an alternative to the digitally-controlled source.

  • Publication number: 20090112633
    Abstract: A system for structuring credit support in connection with life insurance premium finance loans and securitizing longevity risk includes a trust having a life insurance policy and a premium finance loan from a lender that finances the cost of the premiums of the life insurance policy. The life insurance policy is used as collateral for the premium finance loan. The trust provides to the lender additional collateral in the form of a letter of credit or other forms of collateral to cover any shortfall between the balance and the policy cash surrender value. A longevity risk fund provides the credit support by entering into a collateral support agreement with the trust through a credit source. The longevity risk fund receives compensation in the form of risk adjusted return on exposure, in exchange for providing the additional collateral.

  • Publication number: 20090099979
    Abstract: The present inventions provide improved funding and administrative arrangements for increasing the amount of income available for group benefit plans, unions, VEBAs, and other entities designed to aggregate funds for the benefit of a selected population. In general, the arrangement includes an insurance component and a financing component and may be bankruptcy-remote from the group benefit plan and its sponsor. The financing component may be combined with the insurance component in order to create and capture value by obtaining comparatively inexpensive capital market funding to generate a favorable economic outcome for the plan, its participants and/or certain specified beneficiaries. The financing component may be selected such that it is capable of paying premiums associated with the insurance component and funding other aspects of the arrangement.
