P-channel MOSFETs, M1 and M2, are used to implement the input differential pair to achieve a reduced 1/f noise contribution. This is critical for sensing physiological signals with small amplitudes. The input transistors can be biased in subthreshold region to obtain an adequate small-signal transconductance, gm1 or gm2, without consuming a large DC bias current, hence low power dissipation. The low DC bias current will result in a reduced amplifier slew rate, which however can be accommodated in most biomedical applications due to the relatively lowspeed requirements.
