DIFFERENTIAL ANALOG INPUT BUFFER

Abstract:

A differential signal input buffer is disclosed. The differential signal input buffer may receive a differential signal that includes a first signal and a second signal and may be divided into a first section and a second section and. The first section may buffer and/or amplify the first signal based on a first level-shifted second signal. The second section may buffer and/or amplify the second signal based on a first level-shifted first signal. In some implementations, the first section may buffer and/or amplify the first signal based on a second level-shifted second signal. Further, in some implementations, the second section may buffer and/or amplify the second signal based on a second level-shifted first signal.
