The invention discloses a chaotic circuit capable of realizing amplitude-frequency control by a time constant. Integration-summation circuits of three branches are taken as a framework, and three paths of chaotic signals are output through internal feedback circuits of five multipliers and an internal linear feedback item. Through adjustment of resistance or capacitance on a first-dimension linear feedback branch, joint adjustment and control of the amplitudes and frequencies of the chaotic signals output by a system is realized. The amplitudes and frequencies of the chaotic signals output by the circuit are adjusted through rheostats and adjustable capacitors of the branches to realize joint adjustment and control of the amplitudes and frequencies. Joint control of the amplitudes and the frequencies is implemented through two control entries different from other circuits, so that the flexibility of a hardware circuit is enhanced; the circuit implementation and debugging difficulty is lowered; and convenience
