Opis:
This paper proposes a transmit/receive (T/R) nanoswitch in 130 nm CMOS technology for 2.4 GHz ISM band transceivers. It exhibits 1.03-dB insertion loss, 27.57-dB isolation and a power handling capacity (P1 dB) of 36.2-dBm. It dissipates only 6.87 μW power for 1.8/0 V control voltages and is capable of switching in 416.61 ps. Besides insertion loss and isolation of the nanoswitch is found to vary by 0.1 dB and 0.9 dB, respectively for a temperature change of 125°C. Only the transistor W/L optimization and resistive body floating technique is used for such lucrative performances. Besides absence of bulky inductors and capacitors in the schematic circuit help to attain the smallest chip area of 0.0071 mm2 which is the lowest ever reported in this frequency band. Therefore, simplicity and low chip area of the circuit trim down the cost of fabrication without compromising the performance issue.

Opis:
In Bangladesh 164 million people depend on rice but due to climate change (CC) vulnerabilities the yield of rice is severely reducing. Therefore, this study aimed to explore the effects of CC on rice yield using recent trend analysis, Mann-Kendall (MK) trend test and correlation. For this study, the required climate and selected rice production data were collected from Bangladesh Meteorological Department (BMD) and Department of Agriculture Extension (DAE), Khulna. In time series statistics both parametric and nonparametric methods were applied to detect a monotonic trend of climatic variability and Aman rice production. Correlation between climatic variability and rice production was also investigated. The study exposed that the temperature and rainfall had an increasing trend and statistically significant whereas the relative humidity found decreasing. Overall, the bright Sunshine had positive trend but week. According to nonparametric trend test of climatic variability and Aman yield only minimum temperature showed a positive trend which found statistically significant. In contrast, Mann-Kendall trend test revealed that rainfall had positively significant while temperature had negative significant. The correlation revealed the Aman production is a strong response with minimum temperature whereas the Lona Coche showed a positive correlation with maximum temperature. The variation of Aman production exhibited a positive correlation with both Rainfall and humidity respectively and Lona Coche found a negative correlation. The sunshine had a week correlation against both yields. The findings suggest should give attention of temperature-tolerant rice varieties to mitigate possible adverse effects of CC.
