“…If there is little energy available (such as in an RFID tag) the problem becomes quite obvious. A comparison between several types of pulse generators, including logic-based, is presented in [6]. Transistors driven in the avalanche region can be used to generate extremely short pulses but usually require high supply voltages, as mentioned in [7].…”

“…Transistors driven in the avalanche region can be used to generate extremely short pulses but usually require high supply voltages, as mentioned in [7]. For instance, the pulse generator described in [6] uses a supply voltage of 300 V. High voltages are also often linked to avalanche diodes. In fact, the latter is normally only used to generate high-power pulses (necessary for applications like long-range radar).…”

Radio-frequency identification (RFID) tags (passive kind) are typically not designed to include ultra-wide band (UWB) pulse generators, but may be in the future. The reason is that the very short pulses produced by the RFID tags could be used to estimate their positions with errors of solely a few centimetres using time difference of arrival techniques. Currently, the method most commonly used to estimate tag positions relies on received signal strengths (less accurate). An UWB pulse generator based on a PIN diode is presented in this study. This pulse generator was designed to produce a positive unipolar pulse for each high-to-low transition (1.8 V to 0) it receives at its input. This trigger signal is generated by a microntroller-based battery-free RFID tag. The end result is a pulse with an amplitude of ∼300 mV and a duration of slightly <2 ns measured using a 50 Ω load.

Ultra wideband (UWB) radio for communication has several challenges. From the physical layer perspective, a signaling technique should be optimally designed to work in synergy with the underneath hardware to achieve maximum performance. In this paper, we propose a variant of pulse position modulation (PPM) for physical layer signaling, which can achieve raw bitrate in excess of 150 Mbps on a low complexity in-house developed impulse radio UWB platform. The signaling system is optimized to maximize bitrate under practical constraints of low complexity hardware and regulatory bodies. We propose a detector and derive its theoretical performance bounds and compare the performance in simulation in terms of symbol error rates (SER). Modifications to the signaling, which can increase the range by 4 times with a slight increase in hardware complexity, is proposed. Detectors for this modification and a comparative study of the performance of the proposed UWB physical layer signaling schemes in terms of symbol error rates are discussed.

“…The pulse generator is realized using a step-recovery diode based on the circuit characterized in[10], and is triggered by the start signal from the FPGA. The output of the energy detector, after being compared with the voltage threshold in the on-chip comparator, provides the stop signal for the TDC measurement.…”

This paper presents a research activity aimed at developing an Ultra-Wideband sensor for personnel indoor localization, based on the round trip time measurement of Ultra-Wideband pulses. An approach combining flexibility, high measurement update rate and asynchronous operation with digital processing capability has been employed in the design of the sensor. The principle of operation of the proposed sensor, the architecture of the realized in-house test bed and the experimental setup are described and discussed.
