Driving circuit producing DSB-SC modulation signal

A driving circuit, comprising:

• a first capacitor;
• wherein during a sampling operation, the first capacitor is coupled between a first input terminal and a second input terminal of the driving circuit;
• wherein during a transferring operation, an end of the first capacitor receives a voltage and another end of the first capacitor is coupled to a load;
• wherein the driving circuit produces a first driving signal to drive the load, the first driving signal comprises a plurality of first portions with a first polarity and a plurality of second portions with a second polarity, the second polarity is opposite to the first polarity, the first polarity and the second polarity are with respect to the voltage;
• wherein the plurality of first portions and the plurality of second portions form a generalized DSB-SC (DSB-SC:
• Double Sideband with Suppressed Carrier) modulated component of the first driving signal, which is modulated according to an input signal between the first input terminal and the second input terminal.
