8(b) can be included to improve the common-mode rejection of this OTA input stage. 2 Bias circuits The switching threshold voltage of the error amplifiers discussed in Fig. 12 are controlled by the voltage Vamp . This voltage, applied to the body of the nMOS device in the error amplifier, controls the threshold voltage of the nMOS devices in each error amplifier. Through an active feedback loop, Vamp is controlled to set the switching threshold voltage of the error amplifier to VDD /2, as shown in Fig.
Such a common level can be maintained by a resistor, Rb , shown in Fig. 2 Gate-input OTA 25 overall gain of the circuit [4, 17], as long as: Rf ≪ A · (Ri Rf Rb ) where A is the open-loop DC gain of the amplifier. 4 V, Rb is given by: Rb = 2/3 · (Ri Rf ) Thus, a gate-input low voltage OTA can be used with the signal common-mode voltage at VDD /2, and yet maintain the OTA input devices in moderate inversion. Current sources could be used in place of the resistors Rb , as shown in Fig. 7(b) . A DC current, Ipush pushed into the virtual ground nodes will maintain a DC voltage drop across the feedback resistor, Rf , as well as the input resistor Ri .
Therefore a common-mode feed-forward cancellation path ,  is added, as shown in Fig. 8(b), through M5A , M5B , M6 and M3A , M3B . In M3A , M3B and M6 , the gate and the body are connected to each other to obtain a forward bias across the body-source junctions; this pushes these devices towards moderate inversion. The small-signal equivalent circuit of a gain stage of the OTA of Fig. 8(b), is shown in Fig. 10. 5V) M2A M6 M3A M3B IL R1A R1B Von M2B VL Vop M5A M5B Vip Vin M1A M4A M4B Vbn M1B VNR (b) Fig.
