Abstract: This specification discloses a bipolar driver which will charge a capacitive load to substantially the potential supplied to the driver. The driver includes two transistors that couple the load to a source of potential. One transistor is connected in shunt with the load while the other transistor is connected in series with the load and the source of potential. The shunt-connected transistor is used to discharge the capacitive load while the serially connected transistor is used to charge the capacitive load with charge from the source of potential. To allow the capacitive load to be charged to the full potential of the source, the driver includes circuitry which decouples the base of the serially connected transistor from the source of potential and drives the transistor with charge accumulated in the base-toemitter junction of the transistor so that the serially connected transistor will not be turned off until the potential across the capacitive load reaches the potential of the driving source.
