摘要：

In this paper a hybrid multi-tanh bulk-driven input stage OTA for low total harmonic distortion (THD) biomedical G(m)-C applications in weak inversion is presented. The proposed OTA was successfully simulated in an 130-nm IBM CMOS process. The simulations show an open loop gain of 46.4 dB and a unit gain frequency of 125 Hz with only 500 mV of power supply voltage and just 25 nW of power consumption. The transconductance is 24 nS with 300 mV p p of linear input range (HD3 <= -60 dB), which is suitable for low-frequency and low-THD biomedical G(m)-C applications.
