Abstract: Systems, apparatuses and methods include technology that identifies whether a product of first and second digital numbers is associated with a positive value or a negative value. During a first clock phase, the technology sets a first reference voltage to have a first value or a second value based on whether the product is associated with the positive value or the negative value. During the first clock phase, the technology controls switches to supply the first reference voltage to first plates of capacitors. Each of the capacitors includes a respective first plate of the first plates and a second plate. Further, during the first clock phase, the technology controls the switches based on the first digital number to electrically connect at least one of the second plates to the first reference voltage and electrically connect at least one of the second plates to a second reference voltage.

Abstract: Power supplies combining a switching-mode power supply in parallel with a current source can improve maximum load current capability. The current source can be turned on, or the amount of current supplied by the current source increased, when there is a heavy load current demand, for example, when the load current demand is more than the current rating of the switching-mode power supply. The duty cycle of the output stage of the switching-mode power supply can be used to determine the load current demand. The current source may increase the maximum output current of the power supply beyond the maximum output current of the switching-mode power supply. For example, the current source may add 0.5 A to the current capability of a 2.5 A switching-mode power supply.
