Also, a saturation detector receives a gate voltage of the drive transistor and judges the drive transistor saturated if an output voltage is smaller than a preset reference voltage. In addition, a switch connects or disconnects between the power voltage and the gate of the drive transistor in response to the judgment of the saturation detector.

In the CMOS image sensor, the photodetector pixel includes a first reset transistor with a drain connected to a supply voltage and a photodetector diode connected between a source of the first reset transistor and a ground. The dark pixel includes a mirror transistor with a drain connected to the supply voltage and a gate and source connected to a gate of the first reset transistor and a dark photodiode shielded from external light. The dark photodiode is connected between the source of the mirror diode and the ground.

This delays the saturation rate of the CMOS image sensor pixel and enhances the dynamic range thereof.

Abstract: An optical line termination comprises a DC current load, power measurement circuitry, upstream data path circuitry and current mirror circuitry. The current mirror circuitry is connected between the DC current load, the power measurement circuitry and the upstream data path circuitry. The DC current load is connected in parallel with a photodiode of the upstream data path circuitry. The DC current load exhibits a substantially fixed load.

The power measurement circuitry is configured for outputting a power level dependent upon the aggregate current. Accordingly, the optical line termination provides for a non-intrusive solution for measuring optical input power and, thereby, enables the measured optical power to be monitored.

Abstract: A method of obtaining a mass spectrum of elements in a sample is disclosed. Sample precursor ions having a mass to charge ratio M/Z are generated, and fragmented at a dissociation site, so as to produce fragment ions of mass to charge ratio m/z. The fragment ions are guided into an ion trap of the electrostatic or “Orbitrap” type, the fragment ions entering the trap in groups dependent upon the precursor ions M/Z. The mass to charge ratio of each group is determined from the axial movement of ions in the trap. The electric field in the trap is distorted. Ions of the same m/z, that are derived from different pre-cursor ions, are then separated, because the electric field distortion causes the axial movement to become dependent upon factors other than m/z alone.

Abstract: Sol-gel derived monolithic silica columns containing entrapped dihydrofolate reductase were used for frontal affinity chromatography of small molecule mixtures. The output from the column combined with a second stream containing the matrix molecule (HCCA) and was directly deposited onto a conventional MALDI plate that moved relative to the column via a computer controlled x-y stage, creating a semi-permanent record of the FAC run. The use of MALDI MS allowed for a decoupling of the FAC and MS methods allowing significantly higher ionic strength buffers to be used for FAC studies, which allowed for better retention of protein activity over multiple runs.
