摘　　要：The effects of temperature on a two-phase clock-driven discrete-time chaotic circuit are presented.The circuit for temperature analysis consists of two switches for sample and hold,a source follower,and a nonlinear function for nonlinearity in the feedback.The chaotic dynamics of this circuit,such as time series,state transitions,frequency spectra bifurcation diagrams and Lyapunov exponents are analyzed as functions of the temperature.It is confirmed that the dynamics of the chaotic circuit have a temperature dependence.Further,we find that the circuit can generate discrete chaotic signals only within specific temperature regions.
