Image reject mixer, circuit, and method for image rejection
InactiveUS6226509B1Easily signalImprove filtering effectModulation transference balanced arrangementsTransmissionIntermediate frequencyCarrier signal
To reduce the impact of image frequencies generated by mixing an incident carrier signal down to a relatively low intermediate frequency signal used in subsequent signal processing, a mixing frequency is selected such that the generated intermediate frequency signal has a frequency offset relative to DC that is substantially that of a single channel spacing between frequency adjacent incident carrier signals, as shown in FIG. 2. Image rejection is further improved through the integration of a current-driven polyphase filter (36) directly between an input stage (Q1 to Q4) and a mixer stage (Q5 to Q12) of an image reject mixer (FIG. 4) such as to mitigate quadrature divergence between separate in-phase and quadrature paths within the image reject mixer.

InactiveUS20060205013A1High sensitivitySimple structureMaterial nanotechnologyMicrobiological testing/measurementIonic strengthDebye length
Provided is a field effect transistor (FET) type biosensor including a source electrode, a gate, and a drain electrode. A ligand that can bind to a side of a nucleic acid is added to the surface of the gate. In a conventional FET type biosensor, it is difficult to detect a signal within the debye length because a target nucleic acid is directly fixed to the surface of a gate of the conventional FET. However, in the present invention, this problem can be overcome and the debye length can be increased by treating the surface of a gate of an FET sensor with a ligand that can bind to a side of a nucleic acid. The ligand can be adsorbed onto the surface of the gate. In this case, the nucleic acid is adsorbed parallel to the surface of the gate, not perpendicular to the surface of the gate, thus generating an effective depletion region. In addition, hybridization efficiency can be increased because a hybridized sample can be injected into an FET sensor at high ionic strength.
