This paper presents a high linearity operational transconductance amplifier (OTA) base on the technique of mobility reduction compensation, which achieves great linearity improvement and has wide input range at low power consumption. The third-order harmonic distortion (HD3) of the OTA is about &#x2212;65dB at 1MHz for a 1.2-V<inf>pp</inf> differential(More)
This paper presents a high linearity operational transconductance amplifier (OTA). The OTA circuit combines the techniques of the double differential pairs (DDP) and Source-degenerated current mirrors to achieve high linearity in a large GM tuning range. With the Gm values ranged from 60&#x00B5;S to 130&#x00B5;S, the HD3 of the OTA is below &#x2212;69dB at(More)
