  • DIHYDRO-CYCLOPENTA-ISOQUINOLINE SULFONAMIDES DERIVATIVES
    Publication number: 20240092773
    Abstract: The present invention relates to dihydro-cyclopenta-isoquinoline derivatives of formula (I): processes for preparing them, pharmaceutical compositions containing them and their use in treating disorders caused by IgE (such as allergic responses, non-allergic mast cell responses or certain autoimmune responses), and in particular, disorders caused by the interaction of IgE with the Fc?RI receptor.

  • Monolithic transformer compensated circuit
    Patent number: 6822434
    Abstract: A monolithic transformer compensated circuit with enhanced quality factor without significantly increasing noise levels is presented in this disclosure. The technique uses a monolithic transformer and a current source driving current into the transformer secondary winding to achieve loss compensation in the transformer primary. An ac current which is proportional to, and in phase with the voltage applied to the primary winding can be used to achieve theoretically perfect loss compensation at a given frequency in the RF (GHz) frequency range. Examples of circuit applications that are particularly suited to the technique include Voltage Controlled Oscillators (VCO's), Low Noise Amplifiers (LNA's) and Filters. The technique has the added advantage of reducing power consumption in some applications.
