Low noise bandgap reference architecture

A system comprising:

• a power supply terminal;
• a ground terminal;
• a first circuit coupled to the power supply terminal and the ground terminal, the first circuit including an amplifier having a first input terminal, a second input terminal, and an output terminal;
• and
• a second circuit including:
• a first transistor having a first terminal, a second terminal, and a control terminal, wherein the second terminal of the first transistor is coupled to the output terminal of the amplifier;
• a second transistor having a first terminal, a second terminal, and a control terminal, wherein the control terminal of the second transistor is coupled to the first terminal of the second transistor and the control terminal of the first transistor;
• a first switch having a first terminal and a second terminal, wherein the first terminal of the first switch is coupled to the power supply terminal, and the second terminal of the first switch is coupled to the first terminal of the first transistor;
• and
• a second switch having a first terminal and a second terminal, wherein the first terminal of the second switch is coupled to the control terminal of the first transistor and the control terminal of the second transistor, and a second terminal of the second switch is coupled to the ground terminal.
