A Novel Bandgap Reference Voltage Source
Shulin Liu · 2012
Based on analysis of the traditional bandgap reference voltage source,a novel bandgap reference voltage circuit was presented,which satisfied the requirement of modern IC for voltage reference source with small quiescent current,good temperature coefficient,low power,high PSRR and small offset voltage.The circuit was simulated by using Spectre of Cadence and implemented in 0.3 μm bipolar process.Simulation results showed that the circuit achieved low power and good temperature characteristics,and a DC power supply rejection ratio up to 92 dB.
