ABSTRACT:
A voltage reference generating method, source, memory device and substrate containing the same include a voltage reference generator comprised of a bandgap voltage reference circuit including a first complementary-to-absolute-temperature (CTAT) signal and a second complementary-to-absolute-temperature (CTAT) signal. The voltage reference generator further includes a differential sensing device for generating a reference signal substantially insensitive to temperature variations over an operating temperature range by differentially sensing the first and second CTAT signals. The method includes generating first and second complementary-to-absolute-temperature (CTAT) signals and generating a reference signal that is substantially insensitive to temperature variations over an operating temperature range.
