Abstract
This paper presence a comparative analysis of two stage and folded cascode bulk driven operational trans conductance amplifier (OTA) topologies for biomedical applications are presented. A two stage bulk driven OTA and Folded cascoded OTA operated with a 1Vpower supply. Bulk-driven PMOS-transistors as an input differential opamp provides high input common-mode range (CMR). To achieve low power consumption all transistors must be operated in sub threshold region. The test results are carried out in standard gpdk180nm CMOS technologies.
