Patents by Inventor Carlo H. Sequin

Carlo H. Sequin 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).

  • Linear differential charge splitting input for charge coupled devices
    Patent number: 4210825
    Abstract: A charge transfer device includes two channels and a common input structure. The input structure is operated in a manner to divide a charge packet of signal-independent size into two complementary packets for movement along the two channels. A single-channel embodiment employs a similar input structure.

  • Linear load MOS transistor circuit
    Patent number: 4197511
    Abstract: The source-drain resistance of an MOS load transistor (M.sub.2) is linearized by means of a pair of properly designed auxiliary MOS transistors (M.sub.3 and M.sub.4) whose source-drain paths are electrically coupled (conductively or through an amplifier) with the load transistor (M.sub.2). The gate electrode of the load transistor (M.sub.2) is connected to the common node point (N.sub.34) between the auxiliary transistors (M.sub.3 and M.sub.4); whereas the transconductances (.beta..sub.3 and .beta..sub.4) of the auxiliary transistors (M.sub.3 and M.sub.4) are designed such that during operation the resulting feedback signal from the common node point (N.sub.34) to the gate electrode of the load transistor (M.sub.2) reduces its nonlinearity.
