A capacitive load drive circuit may comprise a high current drive amplifier configured to be coupled to a capacitive load during a high current ramp up of the voltage across the capacitive load to a cut off voltage; a low current drive amplifier configured to be connected to the capacitive load during a low current ramp up of the voltage across the capacitive load, from the cut off voltage to a maximum voltage across the capacitive load; and the high current drive amplifier configured to be connected to the capacitive load during a high current ramp down of the voltage across the capacitive load. The low current drive amplifier may be connected to the capacitive load during a period of steady state of the voltage across the capacitive load, intermediate the low current ramp up and the high current ramp down. |
