1. An output signal driver comprising:
a positive output node;
a negative output node;
a power supply input node;
a power supply common node;
a charging capacitor coupled to the power supply input node;
a discharging capacitor coupled to the negative output node;
a current source coupled between the power supply input node and the positive output node;
a current sink coupled between the positive output node and the power supply common node;
a first switch coupled in parallel with the current source;
a second switch coupled in parallel with the current sink; and
a controller coupled to the current source, the current sink, the first switch, and the second switch to apply either complementary constant current pulses or complementary constant voltage pulses to the positive output node,
wherein the output signal driver is part of an implantable medical device, and
wherein the implantable medical device is configured to treat sleep disordered breathing.
