This paper presents an improved band-gap voltage reference circuit design for communication and multimedia systems integration applications. The circuit possesses the characteristics of low-voltage, low-power dissipation and low temperature coefficient and is, thus, suitable for mobile communication and multimedia applications. In order to reduce input voltage and power consumption and to provide the output reference voltage that is resistant to temperature and power supply variations, the design uses a MOS peaking current mirror and an improved cascode current mirror to construct self-biasing circuit. The simulation results show that the design has achieved a minimum power supply of 1.5V. With a 3.3V power supply, the power dissipation is less than 40uw, and within the temperature range from –20C to 70 C, the reference voltage is between 1.3043 ± 0.0005V.
