1. A multi-channel current pulse generator for driving a plurality of loads, each of the loads having a unique positive terminal and a common negative terminal electrically shared by the plurality of loads, the current pulse generator comprising:
a single pulse control transistor for allowing or blocking current pulses through each of the plurality of loads based on a load driver control signal and having a drain terminal connected to the common negative terminal of the loads, a source terminal connected to ground, and a gate terminal for receiving the load driver control signal; and
each load of the plurality of loads has associated therewith:
a load capacitor configured to be charged by a charging circuit and discharged by providing a current pulse to the positive terminal of the respective associated load; and
a charging control transistor for allowing or blocking a charging current to the load capacitor from the charging circuit based on a corresponding charging control signal.
