Abstract
A biphasic pulse output stage is disclosed for an electronic stimulating device, such as a transcutaneous nerve stimulating device capable of effecting suppression of pain by nerve fiber stimulation. Biphasic constant current output pulses are applied to a user through an electrode pair noninvasively positioned at the skin of the user. Microprocessor generated control pulses control generation of the biphasic output pulses at one or more biphasic output stages each of which is associated with an electrode pair, and the generated biphasic output pulses are capacitively coupled from each output stage which also includes a bleeder network for effecting capacitor discharge.
