Abstract: In an electronic device and a method of adjusting a viewing angle of a liquid crystal display (LCD), a face recognition reference is established. The face recognition reference is compared with faces in an image which is captured by a camera unit to locate a matched face. An adjusted viewing angle of the LCD is computed according to a default viewing angle of the LCD and an angle between a perpendicular of the LCD and a line formed by connecting a center of the LCD and a center of two eyes in the matched face. A voltage value is computed according to the adjusted viewing angle, and a voltage is applied to the liquid crystal molecules of the LCD according to the voltage value to change the default viewing angle of the LCD to the adjusted viewing angle.

Abstract: A reference current generation circuit generates a first branch current that varies by a first percentage in response to variations in a first supply voltage and variations in transistor threshold voltage. The first branch current is mirrored to create a corresponding second branch current. A first portion (sub-current) of the second branch current is supplied through a first transistor, which exhibits the transistor threshold voltage wherein the first sub-current varies by a second percentage in response to the variations in the first supply voltage and variations in transistor threshold voltage, wherein the second percentage is greater than the first percentage. A second portion (sub-current) of the second branch current is supplied through a second transistor. The second portion of the second branch current is mirrored to create a reference current (IREF).
