Recently, RSS based gesture detection using Wi-Fi signal has attracted considerable attention. UWB technology offers more features for gesture detection in indoor environments, which can be applied to medical applications to enhance its accuracy, agility and functionality. In this paper, we compare the gesture detection using Wi-Fi signal RSS and gesture detection using various characteristics of...
A 2.4 GHz on-off keying (OOK) transmitter with high data rate up to 136 Mb/s for biotelemetry applications has been designed in a 0.18 μm CMOS process. Power consumption of the transmitter is reduced by 38 percent with the proposed mechanism of switching an oscillator on and off to generate an OOK modulated signal. The TX for 136 Mb/s OOK data has a DC power consumption of 3 mW and an output power...
This paper presents two fully integrated transmitters with embedded antennas to demonstrate on-wafer wireless testing for the first time. The proposed transmitters are intended to not only replace the I/O pins during manufacturing testing but also to serve as process monitoring circuits. The first RF transmitter, operating at 5.5 GHz, utilizes a current-reuse LC oscillator to minimize complexity and...
