Abstract

The present invention provides a class AB output stage for improving the DC gain and the bandwidth in an OTA of two stages with a minimum consumption of power. The proposed topology allows the polarization current to be controlled in the output stage with the bipolar supply of the processed signal. The proposal allows the OTA of two stages to be designed, which only requires a capacitor for guaranteeing a frequency response with a phase margin higher than 45°. Said compensation scheme avoids the use of resistive elements which are sensitive to temperature and variations of the manufacturing process of the integrated circuit.
