Circuit for current supply of electronic appliance from battery - has capacitor connected in parallel to appliance which is charged up across one or more diodes producing voltage drop operated in their passage direction

摘要

The battery used for the current supply, is esp. a solid lithium iodide battery. The working points of the diodes (4) are positioned in the non-linear (curved) region of the diode characteristic curve. The capacitor (3) is provided with a capacitance of between 1 and 10 microfarads. USE/ADVANTAGE - Known type circuit for current supply to electronic unit e.g. quarz analogue watch. Improved so that better matching of current to electronic user appliance is attained.
