Abstract (en)
Systems and methods for generating reference voltages are provided. A representative system comprises a resistor circuit (32); a first switch (SW1) coupled between a first end of the resistor circuit (C) and first power source (Vss); a second switch (SW2) coupled between the first end of the resistor circuit (C) and a second power source (Vcc); a third switch (SW3) coupled to a second end of the resistor circuit (D); a fourth switch (SW4) coupled to the second end of the resistor circuit (D); a first resistor (R1) coupled between the first end of the resistor circuit and the first switch; a second resistor (R2) coupled between the first end of the resistor circuit and the second switch; a third resistor (R3) coupled between the second end of the resistor circuit and the third switch; a fourth resistor (R4) coupled between the second end of the resistor circuit and the fourth switch; and a control circuit (34) for controlling the switches.
