Method and apparatus for an output buffer with dynamic impedance control
View Patent ↗A method and apparatus for an output buffer with dynamic impedance control have been disclosed.
1. A method comprising:
generating an output signal from a node of two stacked P-type transistors and two stacked N-type transistors;
receiving said output signal;
feeding back a first signal based on said received output signal by passing said received output signal through a P-type transistor connected to at least one transistor in said two stacked P-type transistors; and
feeding back a second signal based on said received output signal by passing said received output signal through a N-type transistor connected to at least one transistor in said two stacked N-type transistors.
2. The method of claim 1 wherein said feeding back further comprises a comparison of said received output signal to a reference voltage.
