On the Performance Improvement of OTA in Sub-Threshold Region with Dual Supply
Performance improvement of symmetrical OTA (Operational Transconductance Amplifier) designed with DTMOS transistors in sub-threshold region is presented in this work. The improvement of Gm, noise and dynamic range is realized with double supply voltage. On the other hand, double supply improves f-3dB (cut-off frequency), Gm (transconductance), THD (total harmonic distortion) of designed OTA-C filter. The proposed method is tested through four cases. The proposed technique has been simulated with 0.18μm TSMC process in Cadence environment.
