    Abstract: A super-wide angle lens and a photographing apparatus including the super-wide angle lens are provided. The super-wide angle lens includes a first lens having a negative refractive power and a second lens having a positive refractive power, wherein the first lens and the second lens are disposed in sequential order from an object side to an image side, and wherein the super-wide angle lens has a half view angle of 80 degrees or greater.

    Abstract: A wide-angle lens system includes, in an order from an object side toward an image surface side: a first lens group having positive or negative refractive power; a second lens group having positive refractive power; and a third lens group having negative refractive power. When an object position changes from an infinite distance to a nearest distance, the first and third lens groups are fixed, and the second lens group moves along an optical axis to perform focusing.

    Abstract: Memory devices are provided. A memory device includes a voltage generation circuit that includes an offset compensator configured to receive a reference voltage and an offset code and to link the offset code to the reference voltage. The voltage generation circuit includes a comparator configured to compare the reference voltage linked to the offset code with a bit line pre-charge voltage and to output driving control signals. The voltage generation circuit includes a driver configured to output the bit line pre-charge voltage at a target level of the reference voltage in response to the driving control signals. The voltage generation circuit includes a background calibration circuit configured to generate the offset code for performing control so that a target short current flows through an output node of the driver from which the bit line pre-charge voltage is output. Related methods of generating a bit line pre-charge voltage are also provided.
