Electric circuit comprising at least one switched capacitor and method of operating said circuit

An electric circuit, comprising:

• at least one switched capacitor which is switched via a first parallel circuit of complementary first and second switches controlled by complementary first and second switching pulse trains;
• a switching pulse generator receiving a basic clock signal and generating the first and second switching pulse trains;
• a control circuit coupled to the switched capacitor and structured to receive the two switching pulse trains and, using a reference signal, deliver a control signal;
• and
• a delay circuit within the switching pulse generator, which receives the control signal and delays the first and/or second switching pulse train in accordance with the control signal.

A switched capacitor circuit, comprising:

• a capacitor;
• a first parallel circuit of complementary first and second switches mutually coupled to the capacitor, the first and second switches being controlled by complementary first and second switching pulse trains;
• a control circuit structured to receive the switching pulse trains and deliver a control signal;
• and
• a switching pulse generator that receives a basic clock signal and generates the first and second switching pulse trains, the switching pulse generator including a first delay circuit that receives the control signal and delays the first switching pulse train in accordance with the control signal.
