- Abstract
- Provided is a fully differential signal system including a first amplification unit including first and second output terminals configured to output an output differential signal generated based on an input differential signal and a common mode feedback signal; a common mode detection unit configured to detect a common mode signal included in the output differential signal; a second amplification unit including a feedback signal output terminal configured to output the common mode feedback signal generated based on the detected common mode signal and a reference signal; a first stabilization unit connected between the first output terminal and the feedback signal output terminal; and a second stabilization unit connected between the second output terminal and the feedback signal output terminal. The fully differential signal system stably operates and an operation performance of the fully differential signal system is improved.
