Instead of having the output of the op-amp drive some subsequent stages, it uses a dummy resistive load, supply currents to the opamp are cascoded and drive the subsequent stages in a push-pull fashion. The real load is the 4.7u cap. Is this op-amp topology common? Does it have a name? What are the advantages/disadvantages of doing this?
The other question was about the feedback path specifically. This one is about the topology of using supply currents to drive amplification stages. Yes it's the same circuit, but completely different questions.
