Abstract: A system and method for creating, designing, and deploying World Wide Web-based surveys in a host machine using a standard web browser without requiring the need of a survey creation program at the survey designer's computer. Survey results are viewable in real time. Survey creation is accomplished from a web browser user interface that allows web content objects stored in a database to be selected, customized, positioned, resized and edited. The web content objects include a plurality of elements selectable for constructing a survey within a survey creation engine. The web content objects further include a plurality of survey templates, e-mail invitation templates, survey question and answer types, page design features, multimedia objects, and general purpose objects. Objects from outside the remote database can also be imported for inclusion in the survey.

Abstract: A single bias block for a single or multiple low voltage RF circuits including one or more amplifiers and one or more single or double balanced mixers with compensation for temperature and integrated circuit process parameters. The power supply may be a lower voltage without sacrificing the dynamic range of the amplifier and/or mixer by applying full power supply voltage to the load with the bias applied to the base circuit through an operational amplifier and/or buffer circuit. For the mixer, a lower noise figure may also be realized by moving the gain control impedance from the emitter to the collector circuit. The circuits may be discrete components or part of an integrated circuit. Methods are disclosed for reducing the power supply voltage without affecting the dynamic range of an amplifier, for temperature and process parameter compensation, and for controlling the gain of a mixer without affecting input or output impedance.
