The switch configurations set which of the PD sections are coupled to particular ones of a plurality of matrix outputs provided by the switching matrix. A structure providing switching matrix configuration information is coupled to the second plurality of inputs of the switching matrix to selects specific ones from the plurality of different switch configurations. An output block comprising a plurality of amplifiers is coupled to the plurality of matrix outputs for providing a plurality of amplified outputs, wherein dynamically adjustable combinations of electrical signals from the PD sections are directed to the plurality of amplifiers based on the switch configuration. The configuration selected effectively centers a location of an incident side beam at a center of the side channel PD banks independent of a wavelength (and resulting position) of the beam.

摘要： The present invention provides apparatus, kits and methods for assaying analytes using photoelectrochemical molecules as labels. Specifically, the present invention provides a method for assaying an analyte, comprising: a) contacting a sample suspected of containing an analyte with a reactant capable of binding and/or reacting with the analyte under suitable conditions to allow binding of analyte, if present in the sample, to the reactant; and b) assessing binding and/or reacting between the analyte and the reactant to determine presence and/or amount of analyte in the sample, wherein the reactant, analyte, or additional reactant or additional analyte or analyte analog is labeled with a photoelectrochemically active molecule. The assessing step also comprises converting the photoelectrochemically active molecule with light to an excited state in the presence of an electrode, and assessing an electric current generated by an electron transfer between the excited photoelectrochemically active molecule and the electrode.

摘要： A phase-locked loop includes a phase detector which receives an input signal and a first internal periodic signal and provides a phase signal indicative of a phase difference between the input signal and the internal signal. A rotator then receives the phase signal and provides first and second periodic signals each having a frequency that is a function of the phase difference, the first and second periodic signals being 90 degrees out of phase with each other. An interpolator circuit then linearly combines the first and second periodic signals with third and fourth periodic signals to provide the first internal periodic signal. The interpolator circuit may provide a second internal periodic signal that is 90 degrees out of phase relative to the first internal periodic signal. The phase-locked loop may further include a low-pass filter provided between the phase detector and the rotator.
