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 Cmos Current-mode Multiplier/divider Circuit

Combination of A/D-D/A converters allows implementing multiplier/divider operations. An efficient design based on continuous-time, current-mode, dividing-algorithmic converters is presented in this paper. It offers high speed and capability of low voltage operation, and it is suitable for applications of low or middle resolution (below 9 bits). In addition, the division result is given in both ...
