摘要: A bandgap voltage reference circuit for 0.35-μm, 3-volt CMOS technology operates in an essentially temperature independent manner and having low supply voltages. The incorporates two operational amplifiers. One amplifier biases bipolar devices of the generates a PTAT across resistor, other buffers related to one device generate reference. In embodiment, includes start-up ensure stable desired state. current bias may also be provided. second provide regulated first stage circuit. provides buffered output resistor divider voltages below 1.24-volt voltage. versions, which is optimized potential VDD approximately 1.8 volts standard 2.4 volts.
