A multi-channelelectronic stimulator for spinal cord stimulation including a control circuit,a digital to analog converter, a sampling circuit and a stimulation waveformgenerator. The control circuit providing the digital to analog, the samplingcircuit and the stimulation waveform generator with amplitude control signal,channel selective signal and stimulation type signal respectively. The samplingcircuit outputs stably voltage signal to the stimulation waveform generator,and the stimulation waveform generator outputs stimulation waveform for electricalstimulation therapy. The stimulation waveform generator adjusts the amplitudeof the stimulation waveform by voltage signal, and the stimulation waveformgenerator adjusts the frequency, the polarity, and the width of the pulse bythe stimulation type signal to improve wide application of the multi-channelelectronic stimulator for spinal cord stimulation.一種多通道之脊髓電刺激產生器包含控制電路、數位類比轉換電路、取樣電路及刺激波形產生器,控制電路分別提供振幅控制訊號、通道選擇訊號及刺激類型訊號至數位類比轉換電路、取樣電路及刺激波形產生器,數位類比轉換電路輸出振幅訊號至取樣電路,取樣電路輸出穩定之電壓訊號至刺激波形產生器,刺激波形產生器輸出刺激波形以進行電刺激之治療,刺激波形產生器藉由電壓訊號調整刺激波形之振幅,並藉由刺激類型訊號調整刺激波形之頻率、極性及脈衝波寬,使多通道之脊髓電刺激產生器之應用更加廣泛。100...多通道之脊髓電刺激產生器110...控制電路120...數位類比轉換電路130...取樣電路140...刺激波形產生器150...升壓電路160...電極ACS...振幅控制訊號CSS...通道選擇訊號STS...刺激類型訊號DAC_out...振幅訊號SH_out...電壓訊號Vcp_in...直流電壓clk...時脈訊號Vcp_out...升壓電壓dac_vbias...直流偏壓rst...重置訊號
