| Abstract: | From the stability formula of the base circuit, the stability expression within constant current source and assistant power is discussed. The collector resistance of the comparable-amplifying transistor is substituted by constant current source to bring the effect of amplifying-part into play sufficiently. Moreover, assisted by jarless power supply, the stability of the DC source is improved evidently. This makes the DC-constant voltage source with cut-off protect attained high precision parameter about 10 -5. |
