“…According to (2), if Z 02 g m >> 1, (1+Z 02 g m ) can be simplified to (Z 02 g m ) and, hence, |S 21 | is independent of g m , which results in a highly-linear power gain for the amplifier. Therefore, to achieve a good linearity, the value of g m must be designed to be as large as possible.…”

Abstract-In this paper, a power amplifier implemented with a common-drain structure is introduced. With proper input matching, this structure is shown to provide a reasonable power gain and superior linearity and efficiency in comparison to other low-power topologies. This is shown to be due to the low dependency of the power gain to the transistor transconductance and the low-voltage variations across the gate-source capacitance. This power amplifier is suitable for low-power and short-range applications such as Bluetooth Low Energy (BLE). Based on the calculated S-parameters, the operation frequency of this amplifier and its design trade-offs are presented, along with a comparison with competitive topologies. The design is simulated in a 0.13 m CMOS technology, operates with a 1.2 V supply, and provides a power gain of 8.5 dB with a DC power consumption of 3.6 mW. The input 1-dB compression point is 2.2 dBm, yielding a power added efficiency of 43%.

“…Typical applications of these standards include wireless sensor networks and wirelessly connected electronics running on cell batteries offering tight energy budgets [1][2][3]. As a result, highly power efficient circuitry must be designed in order to attain the power budgets required by the RF transceivers for use in these applications.…”

Abstract. We implement an assisted positioning system, based on BLE and six-axis accelerometer that includes an accelerometer and a gyroscope. The system uses two on-chip CC254x with BLE features for wireless transmission and MATLAB for the data processing in the cloud. After quadratic integral of acceleration data, we get displacement of the moving object. After integral of angular acceleration data, we get rotation angle of the moving object. According to the principle of different coordinate system conversion, combining the displacement and rotation angle, we get the trajectory of the moving object. When applied to GPS signal blocked areas, the system can implement assisted positioning.

Abstract-Condition monitoring (CM) of gearbox is a crucial activity due to its importance in power transmission for many industrial applications. Monitoring temperature is an effective mean to collect useful information about the healthy conditions of the gearbox. This study investigates the use of a novel wireless temperature node to monitor and diagnose different faults on a gearbox transmission system under different conditions. The wireless temperature node was fabricated with a novel feature that it is supplied by a thermoelectric generator module mounted on the gearbox house to be monitored so that the measurement system avoids the shortage of using a wired power sources or the requirement for recharging or changing batteries. Moreover, the temperatures from lubricating oils and housing are modelled empirically to implement a model based detection. The results show that this monitoring approach allows a number of common faults: tooth breakage, oil shortage, and shaft misalignment to be separated under different loads, which demonstrates the outstanding performance of the proposed system and thus suitable for online and automated condition monitoring.
