Abstract:
Disclosed are low power (e.g., nanowatt) voltage regulator circuits and devices, systems and methods using the same for ultra-low power applications, such as, but not limited to, Internet of things (IoT) applications. The disclosed devices and systems relate to low-dropout (LDO) circuits and methods for constructing and using the same. The disclosed LDOs operate with uniform output frequency characteristics over a wide range of load currents.

Claim (Index 1):
A low-dropout regulator (LDO) circuit, comprising:\n an amplifier having a first input and a second input, the first input configured to receive a voltage from a reference voltage source and the second input coupled to an output of the LDO circuit; an output stage transistor coupled to an output of the amplifier, wherein a first terminal of the output stage transistor is coupled to a source voltage and a second terminal of the output stage transistor is coupled to the output of the LDO circuit; an output capacitor connected to the output LDO circuit; and a compensation circuit coupled between the LDO circuit output and the output stage amplifier output, the compensation circuit including at least one capacitor and at least one transistor that introduce a compensation zero in a transfer function of the LDO circuit that substantially tracks and compensates for a first non-dominant pole of the transfer function of the LDO circuit, the transfer function including a dominant pole having a location that is determined at least in-part by a value of the at least one capacitor in the compensation circuit.
