Abstract
A single-ended signal is converted to differential signals with a first device that converts an input current of a single-ended input signal to a voltage, a second device coupled to the first device to generate a first output current of a double-ended output signal based on the voltage, and a third device coupled to the first device to generate a second complementary output current of the double-ended output signal based on the voltage. The output currents can be amplified by a gain with respect to the input current, and the gain can be set a relative size of the first device with respect to each of the second and third devices. A fourth device can balance the current gain of the first device and cause the current through the second device and the third device to be equal.
