  • Low voltage bandgap circuit with improved power supply ripple rejection
    Patent number: 6507179
    Abstract: Methods and apparatus are disclosed for reducing output ripple voltages in bandgap voltage reference circuits. Ripple rejection circuitry is connected to a supply voltage and a first control signal, such as from an amplifier. The ripple rejection circuitry provides a second control signal representative of a difference between the supply voltage and the first control signal. The second control signal is then used to generate a reference voltage output. The incorporation of the supply voltage component in the second control signal operates to reduce or suppress the effects of power supply ripple on the bandgap voltage output.
