| Summary: | 碩士 === 國立臺北科技大學 === 電資碩士班 === 99 === This thesis aims to design a CMOS bandgap voltage reference with a state-up circuit, but without using an operational amplifier. Typically, an operational amplifier was used in bandgap reference to have both great performance and stability. However, a disadvantage of high offset voltage degrades its performance, considerably moreover, an operational amplifier occupies more chip area. In order to overcome those problems, a CMOS bandgap reference without OPA was proposed in this paper, not only having good performance but also reducing the chip area. Furthermore, a start-up circuit and a gm-constant circus are used in the proposed bandgap reference, to realize a zero temperature coefficient, Notify that both temperature-independent voltage and current are provided simultaneously.
