ABSTRACT:
A wide-band amplifier for driving a capacitive load includes an amplifier of a complementary push-pull circuit receiving and amplifying an input signal to produce an output signal for driving the capacitive load, and a controller for controlling bias current of the amplifier in response to a detected output derived from a high frequency component in the output signal of the amplifier. The controller makes the bias current of the amplifier variable with frequency and amplitude of the input signal.
