Abstract
A reference generator circuit included in a computer system may employ multiple field-effect transistors to generate a reference voltage whose value is based on the threshold voltages of the multiple field-effect transistors. The reference generator circuit can include a current source that generates a bias current. One of more stages included in the reference generator circuit can generate, using the bias current, respective output voltages whose values are based on differences in threshold voltages of field-effect transistors included in the stages. The output voltages can be combined to generate different reference voltage values.
