  • Bandgap-less reference generator
    Patent number: 11592857
    Abstract: The bandgap-less apparatus is a fast settling circuit (e.g., with settling time of less than 40 ns) that can leverage proportional-to-absolute-temperature only (PTAT-only) currents to generate a zero or substantially zero temperature coefficient, or even complementary-to-absolute-temperature (CTAT), reference current or voltage, without the need of a native CTAT component or bandgap diodes. The apparatus subtracts two different PTAT currents so that the resulting current is zero-TC. The resulting current is a reference current. The resulting current can be converted to a reference voltage.
