A true class `AB' fully differential current output stage with very high common mode rejection ratio is presented in this study. The operational principle of this unique structure is discussed, its most important formulas are derived and its outstanding ...
The use of dry electrodes is increasing rapidly. Since their impedance is high, there is a high impedance node at the connecting node between the electrode and amplifier. This leads to absorb powerline signal and high CMRR amplifiers are essential ...
A novel circuit topology that provides wideband single-ended to differential conversion is presented. The proposed circuit exploits a negative feedback loop to generate a second input signal for a differential pair, thus obtaining 6 dB extra conversion ...
