Impedance buffer and method |
摘要 |
An impedance buffer has a single comparator with a first input and a second input. A first leg has a first pull-up array in series with a reference resistor. The first input of the single comparator is electrically coupled to a node between the first pull up array and the reference resistor. A second leg has a second pull-up array in series with a pull-down array. The second leg is coupled through a switch to the second input of the single comparator.
