Abstract
Included are embodiments of a 3-level line driver. At least one embodiment of a method includes generating a repetitive wave; receiving an input signal and a complement of the input signal; providing a 3-level output signal; and filtering a feedback signal, the means for filtering including at least one of the following: a 0th order filter, and an even order filter.
Claims20
A 3-level line driver, comprising:
- a wave generator configured to generate a repetitive wave;
- a first integrator configured to receive an input signal, the first integrator further configured to integrate the input signal;
- a second integrator configured to receive a complement signal of the input signal, the second integrator further configured to integrate the complement to the input signal;
- a first comparator coupled to the first integrator and to the wave generator, the first comparator configured to compare the integrated input signal with the generated wave;
- a second comparator coupled to the second integrator and to the wave generator, the second comparator configured to compare the integrated complement of the input signal with the generated wave;
- and
- a filter configured to filter a feedback signal, the filter configured as at least one of the following:
- a 0th-order filter and an even order filter.
