This IP is a silicon-proven analog reference generator including a bandgap (BGR) and PTAT reference voltages, PTAT, constant, and CTAT current sources, and an Analog Test Bus in GlobalFoundries 22nm FDX process. A low drop-out (LDO) regulator is also included in the design to provide internal power supplies of sub-blocks. The PTAT voltage can be used as an analog on-chip temperature sensor, and the test bus can be used for DTF and debugging purposes. The BGR, PTAT, and current mirror blocks can be turned on/off using digital control bits in case it is needed.
