A logarithmic cos-hyperbolic function possessing smooth symmetric nonlinear characteristics is implemented through CMOS-based circuit design using the current mode approach. The nonlinear design is then incorporated in a new third-order chaotic oscillator configuration to produce chaotic oscillations. This chaotic circuit is tuned to develop different attractors through the bifurcation parameter. Moreover, the dynamics of chaos such as antimonotonicity and coexistence of attractors are also depicted in circuit simulation by tuning various controlling parameters. Additionally, some numerical analyses are performed on this dynamic system to justify the existence of chaoticity and attractors\u2019 development. This design has been optimized for low-voltage and moderately high dominant frequency of oscillations. Simulations are done using 180-nm CMOS technology in Cadence Virtuoso. Experimental results are presented to verify the workability of the proposed chaotic system. <\/jats:p>","DOI":"10.1142\/s0218126623501359","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T02:22:31Z","timestamp":1666837351000},"source":"Crossref","is-referenced-by-count":1,"title":["Smooth Nonlinearity Generation with lnCosh and Realization of Chaotic Oscillator"],"prefix":"10.1142","volume":"32","author":[{"given":"Garima","family":"Shukla","sequence":"first","affiliation":[{"name":"Department of Electronics Engineering, IIT(ISM), Dhanbad, Jharkhand 826004, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5674-4656","authenticated-orcid":false,"given":"Sajal K.","family":"Paul","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, IIT(ISM), Dhanbad, Jharkhand 826004, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,11,30]]},"reference":[{"key":"S0218126623501359BIB001","doi-asserted-by":"crossref","first-page":"3031","DOI":"10.1103\/PhysRevLett.70.3031","volume":"70","author":"Hayes S.","year":"1993","journal-title":"Phys.
