Systems and devices for dynamically scaled charge pumping

Systems and devices for dynamically scaled charge pumping are presented. Example embodiments of the disclosed systems of dynamically scaled charge pumping enable regulation of the output voltage at a particular ratio and to dynamically control the ratio based on the input voltage. A charge pumping circuit is enabled by an oscillator. The charge pump oscillator is enabled by the output of a comparator. The comparator compares an input voltage to a comparator voltage, which is a divided version of the output voltage. The output voltage is referenced to a regulated voltage and the comparison voltage is divided between the two voltages by a resistor divider. The regulated voltage remains flat until the input voltage equals the reference voltage. At that point, the regulated voltage will begin to rise and follow the input voltage. Before the reference voltage is reached, the output voltage equals the input voltage multiplied by the resistor divider ratio. Once the input voltage reaches the reference voltage, the difference between the output voltage and the input voltage becomes a constant. More info

Systems and methods of low offset switched capacitor comparators

The disclosed systems and methods of low offset switched capacitor comparator reduce settling errors. The system operates in two major phases. During a first phase, the input voltage is sampled on the input capacitors and a differential amplifier is configured in a unity gain configuration to sample the amplifier offset. During the second phase, the input voltage difference is amplified at the output of the comparator. The amplifier transient sampling error is reduced by shorting the outputs of the differential amplifier for a shorting period at the start of the second phase. A clocked comparator at the output of the differential amplifier provides a fast comparison using internal positive feedback. The differential amplifier should have developed sufficient differential output voltage to overcome the offset of the clocked comparator. More info

Systems and methods of ripple reduction in a DC/DC converter

Systems and devices for ripple reduction in a DC/DC converter are presented. The disclosed systems and methods enable ripple reduction in discontinuous conduction mode (DCM) operation. In DCM, the inductor current peak to peak ripple may be reduced based on the load current. To achieve the reduction of the inductor peak to peak current ripple, a digital counter is used to count the time between consecutive PWM pulses. The digital output of the counter is used to control the pulse width modulation. As the digital output of the counter increases, the PWM on-time decreases. Since the PWM pulse is demanded by the load in DCM mode, the peak to peak inductor ripple is modulated by the counter, or, in turn, modulated by the load current. More info
