A Current

A current source circuit for high-resolution CMOS image sensors is introduced in this paper, which can provide a stable current with immunity from IR-drop along the power and ground wires. In the circuit, two pre-charged floating capacitors controlled by two-phase non-overlap clock are connected between the gate and source of a MOS transistor alternately to maintain a constant V GS of the MOS transistor. In this way, the current flowing through the MOS transistor will be stable and has nothing to do with power level. The post simulation results show that the current supplied by the proposed circuit decreases only by 1.6% when the voltage of the power supply decreases by 30%. The simulations have proved that the proposed circuit can improve the performance of high-resolution CMOS image sensors.

Microscope Objective Lens

The optic axis of an electron microscope objective lens is usually assumed to be straight and co-linear with the mechanical center. No reason exists to assume such perfection and, indeed, simple reasoning suggests that it is a complicated curve. A current centered objective lens with a non-linear optic axis when used in conjunction with other lenses, leads to serious image errors if the nature of the specimen is such as to produce intense inelastic scattering.
