Abstract
A multi-level pulser circuit comprises a set of first input pins for receiving respective positive voltage signals at different voltage levels, a set of second input pins for receiving respective negative voltage signals at different voltage levels, and a reference input pin configured to receive a reference voltage signal intermediate the positive voltage signals and the negative voltage signals. The circuit comprises an output pin configured to supply a pulsed output signal. The circuit further comprises control circuitry configured to selectively couple the output pin to one of the first input pins, the second input pins and the reference input pin to generate the pulsed output signal at the output pin. The control circuitry is further configured to selectively couple at least one of the second input pins and the reference input pin to the output pin during falling transitions of the pulsed output signal between two positive voltage levels, and selectively couple at least one of the first input pins and the reference input pin to the output pin during rising transitions of the pulsed output signal between two negative voltage levels.
