PROBLEM TO BE SOLVED: To provide an electronic circuit controlling the rotation speed of a microgenerator for timepiece movement improved especially in the point of power consumption. SOLUTION: An electronic circuit is provided with 2 inputs G- and G+ connected to a microgenerator 1, quartz oscillators 3 and 4, an energy radiation circuit 9 for regulating the microgenerator 1, energy radiation control means 5, 6, 7, 30 and 31 controlling the energy radiation of the energy radiation circuit as a function of the frequency difference between the signal from the quartz oscillator and the signal from the microgenerator and at least one capacitor C1, C2 and C3 charged by the microgenerator by way of at least one switch and it includes a rectifying and voltage-multiplying circuit 2 rectifying and multiplying the signal from the microgenerator. The control-circuit controlling the switch has at least one flip flop, which memorizes the control state of the switch. |
