Common-Mode Control Techniques for Low Voltage Continuous-Time Analog Signal Processors
نویسنده
چکیده
Fully-Differential (FD) circuits are unavoidable under low voltage power supply conditions. To properly operate FD circuits the use of common-mode feedback is compulsory. The conceptual approach to implement the common-mode feedback circuits is introduced. Furthermore, the use of common-mode feedforward techniques to enhance the common-mode rejection ratio is introduced. It is demonstrated that the simultaneous application of common-mode feedback and common-mode feedforward yields optimal performance with only an additional small overhead cost.
