Abstract
A class AB analog inverter comprising cascoded n-channel (NMOS) and p-channel (PMOS) transistors. The inverter uses complementary devices, of which one or more may be a first transistor in cascode with a second transistor. The first and second transistors may have the same threshold voltage (VT), or may have different threshold voltages. The class AB inverter provides improved slew rate and low power capabilities for use in mixed-signal integrated circuits such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and active filters.
