What kind of circuit is this?

This is for my design project. Prof said it's a tracking circuit but I cannot get any information about it.

I already googled for 'tracking circuit' but nothing meaningful article has been found.

Can you give me some source that can help me to analyze it?

The diodes are in a bridge rectifier configuration. There are 2 connections for AC in and 2 for rectified DC out. I don't understand the meaning of the labels on these connections.

That's known as a diode limiter circuit. Provided the diode forward voltage drops are all the same, Vout will track Vin so long as -3V < Vin < +3V. If Vin exceeds these limit, Vout will simply stay at either +3V or -3V. If the Idc current sources were switched on for a brief time and then switched off again the circuit would function as a sampler/limiter, with Vout disconnected from Vin except during the sampling period.

Just because the diodes are connected the same way they are in a bridge rectifier, doesn't mean they're a bridge rectifier. Rectification has absolutely nothing to do with the purpose or operation of this circuit.
