【 摘 要 】

References(5)Cited-By(3)A switched capacitor bandgap voltage reference circuit capable of sub-1-V operation is presented. The proposed circuit generates a sub-1-V reference voltage with a switched capacitor operation, offering several performance advantages over the current-mode sub-1-V counterpart. The proposed design provides an improved supply rejection and outperforms in the presence of process variation. In addition, the circuit does not require a start-up circuit and the associating trimming circuitry is simplistic and cost effective. The proposed sub-1-V switched capacitor BGR can be a practical sub-1-V reference candidate in ultra deep sub-micron CMOS processes.
