$\tanh x$ (hyperbolic tangent) and $\operatorname{erf} x$ (error function) both have shapes like this. –  Antonio Vargas Jul 8 at 3:46
    
What paper is it about? Why are you looking for such function? –  Gina Jul 8 at 4:12

1 Answer 1

function = Amplitude(1 - Exp[-x/(constant)])

Keep amplitude=1 and adjust constant as per ur need

Look at growth function such as in RC circuit
