A two-stage 3.1to 10.6-GHz ultrawideband CMOS low-noise amplifier (LNA) is presented. In our design, a parallel resistance–capacitance shunt feedback with a source inductance is proposed to obtain broadband input matching and to reduce the noise level effectively; furthermore, a parallel inductance–capacitance network at drain is drawn to further suppress(More)
In this paper, a wireless sensor module (WSM) and network used for cool box temperature monitoring in cold chain logistics is presented. The proposed WSM is implemented by integrating mainly a wireless microcontroller JENNIC 5418 based on IEEE 802.15.4 standard with a thermocouple sensing converter MAX31855. The transmitter power and sensitivity of the(More)
