Method and low voltage CMOS circuit for generating voltage and current references |
摘要 |
A method and a low voltage, complementary metal oxide semiconductor (CMOS) circuit are provided for generating voltage and current references with a low voltage power supply. A voltage generating circuit provides a voltage reference and is formed by a plurality of CMOS transistors and a resistor. An operational amplifier includes a differential pair of CMOS transistors. The first voltage reference is applied to an input of the differential pair of transistors and an output of the differential pair of transistors providing a second voltage reference. The operational amplifier includes a plurality of current reference transistors. A first voltage generating circuit generates a first voltage and a second voltage generating circuit generating a second voltage. The first and second voltage generating circuits are formed by a plurality of CMOS transistors. The generated first and second voltages are applied to the voltage reference generating circuit and current reference transistors.
