Abstract: A switched-capacitor DC-DC converter circuit may convert an input voltage into a desired output voltage level. A comparator may compare a desired voltage level to a divided version of the output voltage. A fully digital control circuit comprising a frequency divider circuit, a counter circuit, a digital control logic circuit and a gain selection circuit may generate a gain value, and a phase generator may convert the gain value into clock phase signals and control settings to control a switch array to select capacitors to produce a desired output voltage.

Abstract: An ADC system may include an ADC, a comparator, a voltage source, a comparator output polarity control circuit and a comparator output counter. An analog input signal may be input to a first input of the comparator, and an output of the voltage source may be input to a second input of the comparator. The comparator may generate an output to the comparator output polarity control circuit, and the comparator output counter may count clock cycles while the comparator output is asserted and may assert a monitor output based on the comparator output counter value. The monitor output may be an interrupt, an alarm or other system alerts and may control system operation.
