Abstract
A wide-band digital buffer formed in a III-V substrate including a first transistor, a second transistor, a pull-up circuit shifts a t signal to a level of the first transistor. A first capacitor receives the signal, and passes at least a portion of the AC component of the signal to the first transistor. A resistor receives a first bias voltage, and passes it to the first transistor. A pull-down circuit shifts a second signal to a level of the second transistor. A second capacitor receives the second signal, and passes at least a portion of the AC component of the second signal to the second transistor. A second resistor receives a second bias voltage, and passes it to the second transistor.
