LOW VOLTAGE LOW POWER FULLY DIFFERENTIAL BUFFER
In this paper a useful CMOS fully-differential buffer topology is presented. The proposed solution, performing the common mode feedback operation, shows a rail-to-rail characteristic, so it is particularly suitable for low-voltage (+/- 0.75V) low-power (< 400 mu W) applications. The simulated results have shown excellent general performance, evaluated in terms of suitable figures of merit.
