摘要：

Two new differential class-AB operational transconductance amplifiers (OTAs) for SC circuits that operate with a supply voltage of less than two transistor threshold voltages are introduced. They make use of a new class-AB pseudodifferential pair to generate signal currents much larger than quiescent currents. Both OTAs have been designed to operate with a supply voltage of V-DD = 1.1 V, using a 0.35 pro CMOS technology. Simulation results for a load capacitance (C-L) of 1 pF show 15 MHz gain-bandwidth product with a quiescent power consumption of 10 muW.
