Compact chaotic oscillator using 1 80nm CMO S technology for its use in true random number generator

This paper presents the design of a discrete time chaotic oscillator for its use in True Random Number Generator(TRNG). This circuit uses a three transistor map that produces V-shape inverse tent map characteristic. This chaotic oscillator is used to produce a TRNG that makes it suitable for its applications in cryptography. The circuit was designed and simulated using 180nm CMOS technology and supply voltage of 1.6V. The use of 180nm CMOS generates high entropy random numbers when the environments change.
