  • Abstract
    A new operational transconductance amplifier working with supply voltages down to 1.3 V has been realized in a standard 0.7-μm CMOS technology. A constant transconductance (within 6% of maximum variation) is ensured for the whole common-mode input range. The input transistors operate in weak inversion. The class AB output stage also has a full voltage swing. The circuit provides a 1.3-MHz gain bandwidth for a power consumption of 460 μW (Cload=15 pF) at a 1.5-V supply voltage
