Abstract
Various embodiments are described that relate to a proportional-integral-derivative controller. The proportional-integral-derivative controller obtains an input voltage and from the input voltage produces an output voltage. Achievement of a particular output voltage can be accomplished through variable resistances in the proportional-integral-derivative controller. To realize these variable resistances, a switching capacitor set can be employed. The switching capacitor set can include individual capacitors with switches. The switches can function with a switching frequency. The switching frequency causes individual capacitors to function with an effective resistance. The resistance can directly correspond to the switching frequency. To change the resistance, the switching frequency can be changed.
