Start up circuit bandgap reference
WebbTherefore, when the bandgap reference voltage generator starts up by itself at an initial driving, a start-up failure does not occur. Thus, other electric elements integrated into an integrated circuit element can be supplied with a rated bandgap reference voltage and thus normally operate. Webb10 apr. 2024 · The bandgap reference (BGR) is a conventional type of VRs with a small temperature coefficient (TC) ... Figure 3 shows the proposed VR circuit, consisting of the primary VR, secondary VR, current mirrors and start-up circuit. All MOSFETs are biased in the sub-threshold region to reduce power consumption.
