In this thesis, we consider analysis tools of spike-trains from various Hyperchaotic/Chaotic spiking oscillators(HCSOs/CSOs). The circuit is constructed by linear one-port sub circuit, impulsive switches and reset voltage source. As parameters vary, the circuit can output a variety of spike-trains.　 First, we analyze CSO with state- and time- dependent impulsive switches in series. Next, we analyze HCSO with state- and time- dependent impulsive switches in series. These circuit has switching rule related to time-dependent switch. Because of this rule, these circuit has characteristics that switching times be some multiple of clock period. There-fore, we can calculate dynamics piecewise exactly, analyze more easily and exactly than us-ing other switching rules. Analysis of dynamics and spike-trains are basic to understanding nonlinear phenomenon. In order to analyze such spike-train dynamics, three tools are used: the return map of the state variable at every firing moment, the histogram of inter-spike intervals and the color recurrence plot of the spike-trains. The Return Map cannot be derived directly from the ISI but can be derived if the state variables is observable. Histogram of ISI is most basic method to consider the ISI characteristics. The Recurrence Plot is known as effective visualization method of complex dynamics as time-series data. Using the Recurrence Plot, we can visual-ize periodicity, stationarity and ISI order.　 Presenting a simple test circuit, typical phenomena are confirmed experimental.
