A temperature-dependent reference works by pre-charging a standard linear CMOS or ferroelectric reference capacitor to a pre-charge voltage that is dependent on temperature. At cold temperatures the pre-charge voltage is higher, resulting in a larger voltage on the reference bit-line. At warm temperatures the pre-charge voltage is lower, resulting in a smaller voltage on the reference bit-line. Both the precise temperature slope and offset pre-charge voltage are selectable.
