Abstract:
1. An initial voltage generation circuit, comprising: a reference voltage generator for generating a plurality of reference voltage candidate groups; a reference voltage selector for receiving the plurality of reference voltage candidate groups, the reference voltage selector comprising: at least one initial voltage level regulator; and a plurality of stabilization capacitors; wherein each initial voltage level regulator of the at least one initial voltage level regulator and a corresponding stabilization capacitor of the plurality of stabilization capacitors are coupled to a corresponding selection switch group of the plurality of selection switch groups, wherein the each initial voltage level regulator is used for generating an inner reference voltage according to an external power-up signal, and the corresponding stabilization capacitor is used for stabilizing the inner reference voltage; wherein the external power-up signal is generated by a power-up unit of a system, the initial voltage generation circuit is applied to the system, and the each initial voltage level regulator utilizes the external power-up signal to simultaneously control switches thereof to generate the inner reference voltage.
