Implementation of Rail-to-Rail Operational Amplifier for Biomedical Applications
This paper proposes gain boosting architecture of a rail-to-rail folded cascaded operational amplifier with CMFB scheme that employing fully differential pair amplifier for applications to biomedical signal process. The proposed rail-to-rail folded cascaded single stage OPA is design and implemented using the TSMC 0.35 μ, m CMOS 2P4M process. Based on simulated and measured results , the chip size is 0.740 × 0.534mm2 with power dissipation about 1.6mW, input common mode votage range from 0V to 3.3 V, maximum DC gain 82 dB, 114 dB CMRR and 86 dB PSRR.
