Abstract: Certain embodiments of the present invention include an apparatus comprising a charge pump, configured to provide an output voltage at an output node of the charge pump, and a charge pump regulator circuit coupled to the charge pump. One such charge pump regulator circuit is configured to control the charge pump to increase the output voltage during a first period of time. Such a charge pump regulator circuit can also cause a node of a circuit coupled to the output node of the charge pump to reach a target voltage level during a second time period.

Abstract: Methods of operating voltage generation circuits include applying a clock signal to a first electrode of a first capacitance having a second electrode connected to a first node of a first current path, applying the clock signal to a second capacitance having a second electrode connected to a gate of a second current path connected in parallel with the first current path and with the second electrode further connected to a first end of a resistance having a second end connected to the second node, passing charge across at least one of the first current path and the second current path while the clock signal has a first logic phase, and mitigating current flow across the first current path and the second current path while the clock signal has a second logic phase opposite the first logic phase, as well as apparatus facilitating such methods.

Abstract: A first switch is closed to initialize a circuit by charging a capacitance of the circuit. A second switch is closed to initialize an amplifier in unity-gain configuration. The amplifier is capacitively coupled to the circuit. The first switch and the second switch are then opened to detect a leakage current of the circuit by detecting a change in an output voltage of the amplifier.

Abstract: Voltage generation circuits are useful in the generation of internal voltages for use in integrated circuits. Voltage generation circuits may include a stage capacitance and a voltage isolation device connected to the stage capacitance. The voltage isolation device may include a first current path between an input and an output of the voltage isolation device through a diode, and a second current path between the input and the output of the voltage isolation device through a gate. The gate is responsive to the contribution of a low-pass filter between the output of the voltage isolation device and the gate, and to the contribution of a high-pass filter between a clock signal node and the gate.
