Abstract: A middle-range (mid) low dropout (LDO) voltage has both sinking and sourcing current capability. The mid LDO can provide a voltage reference in active mode and power mode for core only design to work in a Safe Operating Area (SOA). The output of mid LDO can track IO power and/or core power dynamically. The mid LDO can comprise a voltage reference generator and a power-down controller connected to an amplifier, which output is connected to a decoupling capacitor. The provision of a high ground signal allows the mid LDO provide the sinking and sourcing currents.

Abstract: A method of calibrating a thermal sensor device is provided. The method includes extracting an incremental voltage to temperature curve for a diode array from a first incremental voltage of the diode array at a first temperature. The diode array and a device under test (DUT) which includes a thermal sensor are heated. After heating the diode array, a first incremental temperature is determined from the incremental voltage to temperature curve for the diode array and a second incremental voltage of the diode array after heating the diode array. An incremental voltage to temperature curve is extracted for the DUT from the first incremental temperature, a first incremental voltage for the DUT at the first temperature, and a second incremental voltage of the DUT after heating the device under test. A temperature error for the thermal sensor is determined from the incremental voltage to temperature curve for the DUT.

Abstract: A thermal sensor in some embodiments comprises two temperature-sensitive branches, each including a thermal-sensing device, such as one or more bipolar-junction transistors, and a current source for generating a current density in the thermal-sensing device to generate a temperature-dependent signal. The thermal sensor further includes a signal processor configured to multiply the temperature-dependent signal from the branches by respective and different gain factors, and combine the resultant signals to generate an output signal that is substantially proportional to the absolute temperature the thermal sensor is disposed at.

Abstract: Systems and methods are provided for generating a temperature compensated reference voltage. A temperature compensation circuit may include a proportional-to-absolute temperature (PTAT) circuit, and a complementary-to-absolute temperature (CTAT) circuit, with the PTAT circuit and the CTAT circuit including at least one common metal-oxide-semiconductor field-effect transistor (MOSFET) and being configured to collectively generate a reference voltage in response to a regulated current input. The PTAT circuit may be configured to produce an increase in magnitude of the reference voltage with an increase of temperature, and the CTAT circuit may be configured to generated a decrease in magnitude of the reference voltage with the increase of temperature, wherein the increase in magnitude of the reference voltage produced by the PTAT circuit is at least partially offset by the decrease in magnitude of the reference voltage produced by the CTAT circuit.
