In this paper, we present the study of voltage reference in analog circuits. A voltage reference is an important part of any analog integrated circuit. Transistors in analog integrated circuits must have stable bias currents in order to have stable transconductances. Stable voltage references are usually required to generate these bias currents and are also used in other parts of analog circuits. For an analog circuit to operate reliably, the reference voltage provided to the circuit must be stable over a wide range of temperatures and power supply voltages. This chapter surveys various voltage reference topologies reported in literature and chooses the one which is most appropriate for our application of a fully implantable device (recording system). Transistor and component sizing is carried out, and simulation and test results are reported.
