提出了基于CMOS设计的紧凑离散混沌振荡器的真随机数发生器（TRNG）。采用3晶体管映射电路设计混沌振荡器，以构造近似的v型特征（逆帐篷映射）。从分岔图和瞬态波形的角度对混沌振荡器进行了仿真和检验，表明混沌振荡器具有理想的输出，适合TRNG。TRNG采用混沌振荡器产生随机信号，并通过双振荡器采样和异或增加输出信号的随机性。采用0.18μm CMOS工艺，1.8电压供电，对电路进行了设计和仿真。此外，它被测试为功能输出比特率为23mbps，并通过了NIST套装标准的所有测试方法。提出的TRNG在紧凑和鲁棒随机比特序列中提供了一种潜在的替代方案，适用于各种其他安全应用。
True Random Number Generator (TRNG) based on CMOS designed compact discrete-time chaotic oscillator is presented. The chaotic oscillator was designed using 3 transistors map circuit in order to construct an approximate V-shape characteristic (inverse tent map). Simulation of the chaotic oscillator was described and examined in terms of bifurcation diagram and transient waveform to show that it has a desirable output and suitability for TRNG. The TRNG has been used chaotic oscillator to generate a random signal and increase the randomness of output signal through a dual oscillator sampling method and XOR. The circuit was designed and simulated in 0.18μm CMOS technology with 1.8 voltage supply. Furthermore, it was tested to be functional for output bit rate 23 Mbps and passed all test methods in NIST suit standard. The proposed TRNG exposes a potential alternative in both compact and robust random bit sequence that suitable to various other applications in security.
