Claim 0:
1. A method of generating a voltage waveform at an output, the method comprising:
providing a first DC voltage having a first magnitude (V1), a second DC current (I) having a second magnitude, a third DC voltage having a third magnitude (V3), and a fourth DC voltage having a fourth magnitude (V4), wherein the first (V1) magnitude is higher than the third (V3) and the fourth (V4) magnitude,
coupling the fourth DC voltage to the output followed by coupling the first DC voltage to the output, to bring an output voltage (Vp) at the output to a high level,
decoupling the first DC voltage from the output, followed by coupling the third DC voltage to the output, to obtain a drop of the output voltage (Vp),
coupling a ground potential (V0) to the output following coupling the third DC voltage, and
coupling the second DC current (I2) to the output following coupling the ground potential, wherein the second DC current ramps down the output voltage (Vp).
