Abstract
A DC-DC converter for supplying a sufficient power voltage for solid state watches includes field-effect mode transistors operatively associated with charging and discharging paths of multi-stage capacitors which are primary components of the DC-DC voltage converter. The field-effect mode transistors are responsive to outputs from a level converter which in turn converts its input voltage to charge voltage at the last stage capacitor in response to enable signals. During the initial status of operation, the field effect mode switching transistors and the level converter are driven via the parasitic diodes of the field effect mode transistors, P-N junction type diodes provided for protecting the parasitic diodes from damage, or P-N junction type diodes provided exclusively for initiating purposes.
