GSMC18_VDT_01---GSMC 0.18um VCC Detector
The present IP is a VCC Detector (VDT) circuit. It detects the voltage level of its power supplies, AV18 and AV33. The normal operation voltage levels of AV18 and AV33 are 1.62v~1.98v and 3.0v~3.9v respectively. When the detected voltage AV18/AV33 increases beyond the detection level VR18/VR33, the corresponding output OUTP15/OUTP23 is generated as a high level logic. When the detected voltage AV18/AV33 decreases below the detection level VF18/VF33, the corresponding output OUTP15/OUTP23 is generated as a low level logic. This system consists of two comparator sub-circuits and needs an external bandgap. And the output may be in the wrong voltage level during the power-up phase before the bandgap becomes stable.
