This disclosure is directed to a series Doherty power amplifier including two-transformers. The series Doherty combiner may include a first branch including a main amplifier and a first transformer coupled to a load. In particular, a primary inductor of the first transformer may be coupled to the main amplifier and a secondary inductor of the first transformer may couple to the load. The series Doherty combiner may also include a second branch including an auxiliary amplifier and a second transformer coupled to the secondary inductor of the first transformer. The second transformer may couple to the load via the secondary inductor of the first transformer. As such, the load is coupled in series to the first branch and is coupled in series to the second branch. Moreover, the load is coupled in shunt to the main amplifier and the auxiliary amplifier.

Transformer based series Doherty power amplifier

Radio frequency (RF) transmitters of a device (aggressor device) may unintentionally transmit a high-power output signal to antennas of a receiving device (victim device). In some RF systems, a victim device may have no or little protection between its antennas and transistors in an integrated circuit. Performance or lifetime of the transistors may be negatively impacted due to large voltage swings that may result from the high-power signal received from the aggressor device. To prevent or mitigate impact to performance or lifetime of the transistors due to the large voltage swings, protection circuitry including switches and a direct current (DC) power source (e.g., a charge pump) may be implemented at an input of a receiver of the victim device to shunt the power from sensitive circuit components of the victim device.

Charge pump-enabled circuit protection switch

Systems and methods for conducting critical dimension metrology are disclosed. According to certain embodiments, a charged particle beam apparatus generates a beam for imaging a first area and a second area. Measurements are acquired corresponding to a first feature in the first area, and measurements are acquired corresponding to a second feature in the second area. The first area and the second area are at separate locations on a sample. A combined measurement is calculated based on the measurements of the first feature and the measurements of the second feature.

Low dose charged particle metrology system

A calibration method for calibrating the position error in the point of interest induced from the stage of the defect inspection tool is achieved by controlling the deflectors directly. The position error in the point of interest is obtained from the design layout database.

Embodiments of the present invention relate to a method and apparatus for improving performance of a de-clustered disk array by making statistics on a number and types of active input/output (I/O) requests of each of the plurality of physical disks; dividing the plurality of physical disks at least into a first schedule group and a second schedule group based on the statistic number and types of the active I/O requests of the each physical disk for a predetermined time period, the first schedule group having a first schedule priority, the second schedule group having a second schedule priority higher than the first schedule priority; and selecting, in a decreasing order of the schedule priority, a physical disk for schedule from one of the resulting schedule groups thereby preventing too many I/O requests from concentrating on some physical disks and thereby improve overall performance of a de-clustered RAID.
