Abstract:
A circuit for use in combination with a battery which is adapted to selectively generate a voltage, a first component which is to selectively receive the voltage, and a second component which allows the voltage to be communicated from the battery to said first component, said circuit comprising:a substantially constant electrical source comprising a first transistor having a collector terminal which is coupled to a resistor and a base terminal which is coupled to a device; said resistor being coupled to said substantially constant electrical current source and to said second component and which cooperates with said substantially constant electrical current source to provide a substantially constant amount of biasing voltage which is applied to said second component, effective to cause said voltage to be communicated from said battery to said first component; and a capacitor which is coupled to said battery and to said collector terminal of said first transistor and which is connected to said resistor in parallel fashion.
