SUMMARY

The Gain-Assisted Current Mirror utilizes a diode-connected transistor to create a reference current, essential for maintaining stable current sources in integrated circuits. This configuration is specifically designed to manage voltage drops effectively while ensuring precise current delivery. The left transistor serves a critical role in establishing the necessary voltage drop for optimal operation of the current mirror.

That's basically a current source that gives a reference current.
 
It's called a "diode-connected" transistor and is used, as what says, a current source. You will find them used this way in integrated circuits where small currents sources are required.
