Reference voltage generation circuit with noise voltage suppression for digital mobile device

摘要

The circuit has a current mirror stage (CM) with an input and an output. An input current supply stage (Q3,R3,Q4) connected to the input of the current mirror stage produces a current at the input to the current mirror stage. A switching element (Q6) is connected to the input current supply stage to switch it on and off. An output transistor (Q5) is connected to the output of the current mirror stage to generate a reference voltage. A delay stage formed by a capacitor (C2) is connected to the current mirror stage's output.
