A programmable CMOS bandgap voltage reference circuit using current conveyor

This paper presents a new structure of a bandgap circuit which can be programmed to get any desired output voltage. Unlike conventional bandgap circuits, the proposed bandgap circuit uses MOS transistors operating in subthreshold region instead of bipolar transistors to generate PTAT and IPTAT currents. Use of the current conveyor makes the circuit capable of being operated at lower supply volt...

A VDD and Temperature Independent CMOS Voltage Reference Circuit

A pure CMOS threshold voltage reference (VTR) circuit achieves temperature(T) coefficient of 5 μV/°C (T=-60~+100 °C) and supply voltage(VDD) sensitivity of 0.1 mV/V (VDD=3~5 V). The combination of subthreshold current characteristics and different operating modes in n-MOSFETs provides a small voltage and temperature dependence. A feedback scheme from the reference output to gates of n-MOSFETs n...
