All damping schemes implemented in MINIMOS-NT have in common that they damp the
solution vector by a damping factor d and hence obtain the following new
solution

x^{*} = x^{k} + d^{ . }x^{k + 1} - x^{k}

(6.1)

to replace the undamped new solution
x^{k + 1}. The computation of the
damping factor d depends on the damping scheme selected. Investigations were
made on several damping schemes and potential damping was found to deliver
most reliable results [15].

the update norm of the potential sub-vector, and V_{T} the thermal voltage. A larger
results in more logarithm-like damping of the updates.
