1. A medical device system comprising a medical device, the medical device including a therapy delivery circuit configured to:
generate an electrical stimulation pulse signal that oscillates throughout a pulse width;
modulate the oscillations of the stimulation pulse signal between at least one of:
a maximum frequency and a minimum frequency that is different than the maximum frequency; or
a maximum offset and a minimum offset of a bias of the electrical stimulation pulse signal, the minimum offset being different than the maximum offset; and
modulate an amplitude of the electrical stimulation pulse signal between a minimum amplitude and maximum amplitude during the pulse width so that the maximum amplitude is at a time during the pulse width of at least one of:
the minimum frequency of the oscillations of the stimulation pulse signal; or
the maximum offset of the bias of the electrical stimulation pulse signal; and
deliver the modulated electrical stimulation pulse signal to a stimulation electrode.
