Patents by Inventor Trygve Willassen

Trygve Willassen 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).

  • Patent number: 7541871
    Abstract: Apparatus and methods provide an operational transconductance amplifier (OTA) with one or more self-biased cascode current mirrors. Applicable topologies include a current-mirror OTA and a folded-cascode OTA. In one embodiment, the self-biasing cascode current mirror is an optional aspect of the folded-cascode OTA. The self-biasing can advantageous reduce the number of biasing circuits used, which can save chip area and cost. One embodiment includes an input differential pair of a current-mirror OTA.

  • Patent number: 7532498
    Abstract: A ferroelectric memory comprises a plurality of memory cells and circuitry to sense data thereof. Power supply decoupling circuitry may decouple supplies of the memory device during a portion of reading data. Additionally, ferroelectric domains of the memory cells may receive a series of polarization reversals to improve domain alignment and malleability. To drive reference cells of the memory with such polarization reversals, a multiplexer may be configured to swap a data bitline with a reference bitline so that reference cells may be accessed as regular data cells. While reading a ferroelectric memory, a self-timer circuit may monitor characteristics of the ferroelectric material and adjust an integration duration for a sense amplifier based on the monitored characteristics. A sampling-comparator may sample a signal related to the ferroelectric material at one instant, which may then be used subsequently thereafter by the self-timer circuit to influence an integration duration of the sense amplifier.
