Abstract: In certain aspects, a method for voltage regulation includes adjusting, using a feedback circuit, a resistance of a first pass element in a direction that reduces a difference between a reference voltage and a feedback voltage, wherein the first pass element is coupled between an input and an output of a voltage regulator, and the feedback voltage is equal to or proportional to a voltage at the output of the voltage regulator. The method also includes adjusting a bias voltage of the feedback circuit in a direction that reduces the difference between the reference voltage and the feedback voltage.

Abstract: An apparatus and method for generating a temperature-compensated reference voltage are disclosed. The apparatus generates substantially equal temperature-compensated currents by controlling (through negative feedback) voltages across separate resistors through which the currents flow, respectively. Two of the temperature-compensated currents are formed by combining (e.g., summing) a complementary to absolute temperature (CTAT) current (ICTAT) and a proportional to absolute temperature (PTAT) current (IPTAT). A reference voltage VREF is produced by configuring the other the temperature-compensated current to flow through an output resistor.
