Abstract
In one embodiment, a fan out buffer has the inputs of a plurality of output followers connected to the output of a plurality of distribution gates.
Claims17
A fan-out buffer comprising:
- a first differential amplifier coupled to receive an input signal and responsively form a first output signal on a first output;
- a second differential amplifier coupled in parallel with the first differential amplifier to receive the input signal and responsively form a second output signal on a second output;
- a first output follower coupled to the first differential amplifier to receive the first output signal and coupled to the second differential amplifier to receive the second output signal;
- a second output follower coupled to the first differential amplifier to receive the first output signal and coupled to the second differential amplifier to receive the second output signal, the second output follower having an output coupled to a first output terminal of the fan-out buffer;
- and
- a third output follower coupled to the first differential amplifier to receive the first output signal and coupled to the second differential amplifier to receive the second output signal.
