An interleaved ring oscillator includes a first ring oscillator having n stages, and a second ring oscillator having n stages, wherein each stage includes a nfirst gated inverter in the first ring oscillator and a nsecond gated inverter in the second ring oscillator, such that output from the nfirst gated inverter enables the nsecond gated inverter, and output from the nsecond gated inverter enables the nfirst gated inverter.

Interleaved ring oscillator for non-overlapping clock

A boost converter includes a clock generator, a switching converter, a hysteretic controller, and a power tracking module. The clock generator configured to output a clock signal; The switching converter configured to operate at a frequency based on the clock signal. The hysteretic controller configured to regulate an intermediate output from the switching converter. The power tracking module configured to change a frequency control signal that is sent to the clock generator, the change in frequency is based on a current flowing into an output capacitor such that a charge time of the capacitor is minimized when the current is maximized.

Hysteretic control of a boost converter

A sensor system includes a pixel array, a DC/DC converter, and a photodiode stack. The pixel array is configured to operate in an image capturing mode or an energy harvesting mode. The DC/DC converter is configured to convert energy captured by the pixel array while in energy harvesting mode. The photodiode stack is located adjacent to the pixel array and configured to provide power to the DC/DC converter.
