Operational amplifier.

摘要

An op-amp comprising a single gain stage amplifier cascaded with a buffer and an output stage. The buffer comprises an amplifier which isolates the gain stage from the output stage to prevent loading of the gain stage and create a more linear op-amp. For frequency compensation, the op-amp utilizes MOSFETs connected in a reversed biased configuration as load compensation capacitors. This technique reduces the non-linear effects of MOSFET gate capacitors utilized in conventional Miller compensation schemes and allows for digital fabrication technology of low distortion, low power supply operational amplifier design. <IMAGE>
