High Linearity and Efficien
نویسندگان
چکیده
An overview on linearity and efficiency performance optimisation in power amplifier (PA) is presented, stressing the required trade-off demanded to PA designers. For efficiency improvement, the harmonic tuning strategies are discussed, with their advantages and major drawbacks. For linearity improvement, the IMD sweet spot optimisation strategies is presented as a solution to obtain low intermodulation near PA saturated condition, resulting in efficiency enhancement with respect to back-off approaches.

Design of High Sensitivity and Linearity Microelectromechanical Systems Capacitive Tire Pressure Sensor using Stepped Membrane
This paper is focused on a novel design of stepped diaphragm for MEMS capacitive pressure sensor used in tire pressure monitoring system. The structure of sensor diaphragm plays a key role for determining the sensitivity of the sensor and the non-linearity of the output.First the structures of two capacitive pressure sensors with clamped square flatdiaphragms, with different thicknesses are inv...
متن کاملReflectionles grating couplers for Silicon-on-Insulator photonic integrated circuits
We propose a novel grating coupler design which is inherently reflectionles by focusing the reflecte light away from the entrance waveguide. The design rules for this reflectionles grating coupler are explained and the grating coupler design is investigated by means of 3D FDTD simulations for the case of a Silicon-on-Insulator based platform.

Background and Aims: As a method for the diagnosis and management of sepsis, the serum procalcitonin assay is routinely used, especially in the emergency department (ED) and intensive care units (ICU). Procalcitonin has reasonable diagnostic accuracy for bacteremia in hospitalized patients of all age groups with suspected infection or sepsis. This study aimed to compare the Getein Biotech proca...
متن کاملRepairing high school timetables with polymorphic ejection chains
This paper introduces polymorphic ejection chains, and applies them to the problem of repairing time assignments in high school timetables while preserving regularity. An ejection chain is a sequence of repairs, each of which removes a defect introduced by the previous repair. Just as the elements of a polymorphic list may have different types, so in a polymorphic ejection chain the individual ...
متن کاملHigh-Accurate Low-Voltage Analog CMOS Current Divider Modify by Neural Network and TLBO Algorithm
A high accurate and low-voltage analog CMOS current divider which operates with a single power supply voltage is designed in 0.18µm CMOS standard technology. The proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. The proposed divider is modeled with neural network while TLBO algorithm is used to optimize it. The proposed optimiza...
