A circuit for activating a capacitive MEMS structure is provided, with the capacitive MEMS structure having an oscillator element and an electrostatic excitation unit with a first input connection and a second input connection. The circuit includes a high voltage generator, a first pump capacitor, a second pump capacitor, a control unit, and a low voltage operation amplifier. The high voltage generator generates a high voltage and connects to the first input connection and the second input connection. The first pump capacitor is connected to the high voltage generator and includes a first connection connected to the first input connection. The second pump capacitor connects to the high voltage generator and includes a first connection connected to the second input connection. The control unit connects to a second connection of the first pump capacitor and a second connection of the second pump capacitor. The low voltage operation amplifier connects to the control unit.
