ABSTRACT:
A transistorized amplifier includes an active network having a succession of DC coupled transistors, a load resistor across which an output voltage is developed in response to current flowing through the active network and a voltage divider network for distributing an applied DC potential equally across the active network. Each stage in the active network is thereby allowed to operate over only a restricted voltage range, while yet operating cooperatively to control high voltages, using inexpensive low voltage rating components. The amplifier preferably includes at least two sets of active networks, load resistors and voltage divider networks, each set being responsive to a complementary input signal current to provide complementary output voltages useful in driving a pair of electrostatic deflection plates.
