Aspects of the subject technology relate to a circuit for reducing random-telegraph noise in bandgap circuits. The circuit includes a number of diodes coupled in parallel at their respective first nodes to a ground potential. A number of switches are coupled to respective second nodes of the diodes. The circuit further includes a first resistor and a resistor voltage divider. The first node of the first resistor is coupled to a first node of a current source, and the first node of the resistor voltage divider is coupled to the first node of the current source. The switches are used to implement cyclic switching of the diodes in response to a train of pulses. An output voltage of the circuit is derived between a mid-node of the resistor voltage divider and a second node of the first resistor.
