ABSTRACT:
A voltage generator and methods thereof are provided. The example voltage generator may include a voltage comparison block which generates an output voltage in response to a read command, the output voltage corresponding to a difference between a reference voltage and a determination voltage and a voltage generation block which outputs the determination voltage and a comparison voltage in response to the read command, an inverse read command having a phase opposite that of the read command, a switching pulse signal and the output voltage. A first example method may include outputting a determination voltage and a comparison voltage in response to a read command, an inverse read command having a phase opposite that of the read command, a switching pulse signal and an output voltage, the output voltage generated in response to the read command and corresponding to a difference between the reference voltage and the determination voltage. A second example method may include maintaining a comparison voltage at a first voltage level if a read command is disabled and transitioning the comparison voltage to a second voltage level if the read command is enabled by discharging electric current along a first path, the first path connected to a first node coupled to at least one resistor, and a second path, the second path connected to a second node coupled with a switched capacitor circuit, the switched capacitor circuit including a capacitor which is selectively connected to the second node in response to the enabled read command.
