Why use power budget will let current to be 3mA

can anyone tell me why exactly he assumed current in power budget is 3mA

[@RohitSharma-vu6bt]

It is because in the specifications the power dissipation was 10mW and Vdd was 3V. So if you divide power dissipation by Vdd the current in the circuit should be arround 3.3mA for which he allocated 3mA for the circuit and rest 330uA for biasing.
