Abstract
Systems and methods for providing one or more reference currents with respective negative temperature coefficients are provided. A first voltage is divided to provide a divided voltage, which is compared to a reference voltage (e.g., a bandgap reference voltage) to provide a control voltage. The first voltage and the one or more reference currents are based on the control voltage.
