Computation of logarithm of arbitrary base. a Block diagram of a circuit to compute natural logarithm based on the area hyperbolic tangent series approximation of order l=10. b The hyperbolic regime obtained from covalent modification cycle. c Block diagram of a circuit to compute logarithm of arbitrary base by taking the ratio of two natural logarithms. d Simulation results for (i) log105. (ii) log28. (iii) ln5. (iv) ln8. (v) ln10. (vi) ln2. In all simulations, Green dashed-dot line: using area hyperbolic tangent series approximation up to order 10. Black solid line: using hyperbolic regime from the covalent modification cycle
