Patent number: 7400200Abstract: An integrated circuit including a distributed amplifier is disclosed. The integrated circuit includes a plurality of amplification stages, each stage connected to an input signal and an output signal. At least one amplification stage includes an amplification transistor such as a field effect transistor (FET) having a gate, a source, and a drain, the gate connected to the input signal and a feedback path between the drain and the gate.

Patent number: 6879224Abstract: A filter and impedance matching network uses acoustic resonators in place of capacitors. A resonator, e.g. FBAR, behaves similar to a capacitor outside of its resonant frequency and so does not impact the function of the network, outside of its resonant frequency. At this resonant frequency, the resonator quickly transitions from capacitor to short circuit to open circuit and back to capacitor. Thus, the will deliver open and short circuits independent of the standard LC filter resulting in a structure with an additional notch, a notch with the characteristics delivered by a very high quality resonator. This notch can be much sharper and closer to the pass band than is possible with ordinary inductors and capacitors.Type: GrantFiled: September 12, 2002Date of Patent: April 12, 2005Assignee: Agilent Technologies, Inc.Inventor: Michael L.

Patent number: 6803835Abstract: A component that includes a first structure that is integrated with a second structure. The first structure is a lumped balanced to unbalanced circuit (balun) and the second structure is a resonator-based filter. The function of the balun is to move a signal from a differential form to a single ended form or from a single ended form to a differential form. The component has an area that is comparable to the area needed to implement the balun alone. However, the component now provides a filter function. Preferably, the substrate of the first structure also acts as a substrate for the second structure.Type: GrantFiled: August 30, 2001Date of Patent: October 12, 2004Assignee: Agilent Technologies, Inc.Inventor: Michael L.

Patent number: 5236846Abstract: A method for determining ectopic pregnancy in pregnant persons comprises obtaining a test sample; and determining the absence of a fetal restricted antigen in the sample. The sample is obtained from the vaginal cavity in the vicinity of the cervical canal or the cervical os. One fetal restricted antigen is fetal fibronectin. In one embodiment of this invention, the sample is contacted with an insoluble support to which anti-(fetal restricted antigen) antibody is adhered, and the fetal restricted antigen binding to the support is determined. Alternatively, a class of substances of which the fetal restricted antigen is a member is captured with a general binding antibody such as an anti-(fibronectin) antibody; an anti-(fetal restricted antigen) antibody such as anti-(fetal fibronectin) antibody is bound to the support; and the absence of binding with fetal restricted antigen is determined. Competition or sandwich assay procedures can be used. Reagents and reagent kits are also included.Type: GrantFiled: July 18, 1991Date of Patent: August 17, 1993Assignee: Adeza Biomedical CorporationInventors: Andrew E. Senyei, Nelson N. H. Teng
