摘要：

This paper proposed a design of balanced/symmetrical operational transconductance amplifier (OTA) in 90nm that adopting bulk-driven technique. The proposed OTA have been designed and simulated carefully using Synopsys HSpice software and the results are analyzed thoroughly. By implementing bulk-driven technique into symmetrical OTA, it produced open loop DC gain of 29.6 dB, CMRR of 51.48 dB and consumed only 4.296 mu W from +/- 0.5 V supply voltage. This low-power characteristic made the designed OTA suitable to be implemented in bio-medical field where it can be used to amplify the bio-potential signals such as electrocardiogram (ECG) signals.
