    Abstract: The present disclosure describes an image forming element having a semiconductor chip with micro-electro-mechanical-system (MEMS) devices and voltage generators, each voltage generator being configured to generate a voltage used by one or more of the MEMS devices. A floating ground may be used to add a voltage to the voltage generated by the voltage generators. The semiconductor chip may include electrical connections, where each voltage generator is configured to provide the voltage to the one or more MEMS devices through the electrical connections. The MEMS devices may define a boundary in the semiconductor chip within which the MEMS devices, the voltage generators, and the electrical connections are located. Each MEMS device may generate an electrostatic field to manipulate an electron beamlet of a multi-beam charged particle microscope. The MEMS devices may be organized into groups based on a distance to a reference location (e.g., optical axis) in the semiconductor chip.

  • Publication number: 20090085664
    Abstract: By making use of two common-source amplifying units having a shared DC bias in conjunction with two current units or an extra amplifying unit, a power amplifier is capable of providing a high output power in a high power-gain operation and achieving a low power biasing consumption in a low power-gain operation. The two current units are utilized to provide auxiliary bias currents for diverting part of two bias currents corresponding to the shared DC bias for the two amplifying units so that the output power can be boosted in the high power-gain operation. Also, the extra amplifying unit can be coupled in series with the two amplifying units for improving the output power of the power amplifier in the high power-gain operation. The shared DC bias provides same bias current to the two amplifying units for achieving the low power biasing consumption in the low power-gain operation.
