Description
This op-amp is designed for on chip signal processing, especially as a low-noise input amplifier. It uses pole splitting for
compensation. Stable operation at unity gain frequency is not feasible due to the three stage amplifier architecture. The
results are simulated with extracted parasitics. To adapt this op-amp to other demands, scale the output stage and the
Miller-caps or change the bias currents.
