摘要： A charge pump regulator circuit includes an oscillator and one or more charge pumps. One or more oscillating signals are generated by the oscillator. Each oscillating signal has a peak-to-peak amplitude that is variable dependent on a variable drive signal. For some embodiments having multiple oscillating signals, each oscillating signal is phase shifted from a preceding oscillating signal. For some embodiments having multiple charge pumps, each charge pump is connected to receive a corresponding one of the oscillating signals. Each charge pump outputs a voltage and current. For some embodiments having multiple charge pumps, the output of each charge pump is phase shifted from the outputs of other charge pumps. A combination of the currents thus produced is provided at about a voltage level to a load.

摘要： Various methods and devices that involve power-on-reset (POR) circuits are disclosed herein. An exemplary POR circuit for generating a POR signal upon detecting that a supply voltage has reached a desired level comprises a sense circuit and a delayed buffer. The sense circuit comprises: (i) an inverter powered by a known bias voltage; (ii) a feedback circuit powered by the supply voltage; and (iii) an output node of the sense circuit that experiences a voltage transition when the supply voltage has reached the desired level. The delayed buffer is coupled to the output node of the sense circuit that generates the POR signal in response to the voltage transition. The feedback circuit shuts off the sense circuit in response to the voltage transition. The POR circuit generates the POR signal for a local system. The known bias voltage is provided by an external system.
