Dissipation and fluctuations of CMOS ring oscillators close to criticality
Ashwin Gopal, Massimiliano Esposito, Jan Meibohm
We analyze a thermodynamically consistent model of CMOS-based ring oscillators near the onset of coherent voltage oscillations. For driving voltages close to the critical value, we…

Information thermodynamics for Markov jump processes coupled to underdamped diffusion: Application to nanoelectromechanics
Ashwin Gopal, Nahuel Freitas, Massimiliano Esposito
We extend the principles of information thermodynamics to study energy and information exchanges between coupled systems composed of one part undergoing a Markov jump process and a…

Thermodynamic cost of precise timekeeping in an electronic underdamped clock
Ashwin Gopal, Massimiliano Esposito, Nahuel Freitas
Clocks are inherently out-of-equilibrium because, due to friction, they constantly consume free energy to keep track of time. The Thermodynamic Uncertainty Relation (TUR) quantifie…
