摘要：

This letter presents a new low-voltage class-AB differential linear OTA. The proposed transconductor uses a novel scheme based on two cross-coupled class-AB pseudo-differential pairs biased by a Flipped Voltage Follower [ 1]. The transconductor has been designed using a 0.8 mum CMOS technology to operate at 2 V supply voltage with only 260 muW of quiescent power consumption. Simulation results show 90 MHz bandwidth with more than two decades of transconductance tuning range.
