In this paper, we deal with a problem to capture a target by linear multi-agent systems where the agents behave autonomously, whereas the target escapes with a reasonable strategy. We give necessary and sufficient conditions or sufficient conditions for the success of the capturing for several cases. The conditions clarify the performance competition between the target and the agents and we propose...
This paper presents a wideband LC-based VCO using a divide-by-fractional-N injection-locked frequency divider (ILFD), and the fractional-N division is realized by the proposed modulated injection technique. The feedback modulation of incident signals eliminates unwanted injections, which contributes to enlarge the locking range. The ILFD consists of a 2-stage differential ring oscillator, which achieves...
This paper presents a LC-based sub-harmonic injection-locked frequency quadrupler which multiplies a 15 GHz input to 60 GHz quadrature(I/Q) output signals. The proposed quadrupler can use a lower-frequency PLL for incident signal than doublers and triplers, which is very advantageous to implement a wide-tuning and low-phase-noise PLL. The proposed frequency quadrupler is implemented by using a 65...
This paper proposes a novel wideband voltage-controlled oscillator (VCO) for multi-band transceivers. The proposed oscillator has a core VCO and a tuning-range extension circuit, which consists of an injection-locked frequency divider (ILFD), and flip flop dividers. The 2-stage differential ILFD can generate quadrature outputs, and it realizes 2, 3, 4, and 6 of divide ratio with very wide output frequency...
