Claim 0:
1. A voltage conversion circuit, comprising:
a first input module, connected to a first voltage, and having a first input terminal for receiving an input signal and outputting a conversion signal, wherein a high level of the input signal is a second voltage which is less than the first voltage;
a second input module, connected to the first input module, and having a second input terminal and an output terminal, wherein the second input terminal is configured to receive a sampling signal, and the second input module is configured to sample the conversion signal according to the sampling signal and output an output signal via the output terminal of the second input module; and
a latch module, having an input terminal connected to the output terminal of the second input module, and configured to latch the output signal;
wherein the latch module comprises:
a second inverter, having an input terminal connected to an output terminal of the voltage conversion circuit, and an output terminal connected to an output terminal of the latch module; and
a feedback inverter, having an input terminal connected to the output terminal of the latch module, and an output terminal connected to the output terminal of the voltage conversion circuit;

wherein when the sampling signal is in an enabled state, the feedback inverter is in a turned-off state;
wherein the first input module comprises:
a first P-type transistor, having a gate connected to the first input terminal and a source connected to the first voltage; and
a first N-type transistor, having a gate connected to the first input terminal and a source connected to a ground terminal;

wherein a value of the second voltage is such that a pull-up capability of the first P-type transistor is less than a pull-down capability of the first N-type transistor.
