In the modern world the low power supply voltage circuits are major attractable to the most extent because of the long battery runtime for the portable devices like the mobiles, laptops etc. the reduction of the power supply voltage has became the one of the most challenging issue in the VLSI technology industries. So voltage reference circuits are used to reduce the supply voltage because they can operate in the low supply voltage. The voltage reference circuits play an important role in the analog systems. The voltage reference circuit is a simple device having the one simple functionality that is it generates the exact output voltage without depending on the factors like input supply voltage, load current and the temperature change. The voltage reference provides the recommended output voltage which is needed by the circuit for its required measurements. In this paper the different types of voltage reference circuits are discussed and the literature review of the technologies used in different voltage reference circuits have been performed and comparison of different technologies have been performed.
