“…In the present paper, a voltage mode stimulation was adopted. Specifically, it was more efficient to use a voltage-mode stimulation in high-current stimulators (such as pacemakers and spinal cord stimulators) compared to current mode stimulation [37]. The setting of the voltage index is related to the safety current passing through the human body, the skin impedance of the human body, and the tolerance of the patients' acupuncture site.…”

“…This can be done by the voltage or current mode stimulation. Voltage mode stimulation is more efficient due to the setting of the supply voltage near to the output voltage [3]. However, due to the changes of the electrode-tissue impedance, the stimulation charge cannot be controlled accurately.…”

In this paper, a low-power and precise electrical stimulator is introduced in which no operational amplifier (OPAMP) is used. For electrical stimulations that have low pulse width, an OPAMP with high slew rate is needed which is power consuming. In this work, the OPAMP is substituted with a digital circuitry. A 100 KHz clock is also used to update the current of the stimulator in the stimulation phases in order to make the stimulator accurate enough. Producing such a clock needs only few micro watts. This stimulator is simulated in a 0.18 μm CMOS process, as well. The simulation results shows that this stimulator has only 0.056% charge mismatch in 1 mA stimulation current with a pulse width of 32 μs.

Abstract. This paper developed a novel electrical stimulator. This electrical stimulator, based on wrist-ankle acupuncture in traditional Chinese medicine and transcutaneous electrical nerve stimulation (TENS), aimed at reliving pains. The electrical stimulator has wide band voltage adjustment (0V-100V with 3.3V power supply) with voltage-mode electrical stimulation (ES) circuit. The novel topology of the circuit was implemented without operational amplifier (OPAM) and the transformer was used. A boost converter was applied in the circuit to produce treatment voltage, meanwhile an H-Bridge to produce the required biphasic pulses to effectively reduce the tolerance and polarization reaction. The low treatment voltage was used to make this circuit safer for users. The circuit tests were carried out and a pain model was established on healthy volunteers. The experiment suggested that the stimulator had good effect on pain relief and meanwhile increased the pain threshold.
