A switched capacitor (SC) is an electronic circuit that implements a function by moving charges into and out of capacitors when electronic switches are opened and closed. Usually, non-overlapping clock signals are used to control the switches, so that not all switches are closed simultaneously.

What Is a Switched-Capacitor Circuit? A switched-capacitor circuit is a discrete-time circuit that exploits the charge transfer in and out of a capacitor as controlled by switches. The switching activity is generally controlled by well-defined, non-overlapping clocks such that the charge transfer in and out is well defined and deterministic.
The control circuit consists of an oscillator and the switch drive signal generators. Most IC switched capacitor inverters and doublers contain all the control circuits as well as the switches and the oscillator. The pump capacitor, C1, and the load capacitor, C2, are external.

The switches used in IC switched capacitor voltage converters may be CMOS or bipolar as shown in Figure 4.9. Standard CMOS processes allow low on-resistance MOSFET switches to be fabricated along with the oscillator and other necessary control circuits. Bipolar processes can also be used, but add cost and increase power dissipation.
There are three general techniques for adding regulation to a switched capacitor converter. The most straightforward is to follow the switched capacitor inverter/doubler with a low dropout (LDO) linear regulator. The LDO provides the regulated output and also reduces the ripple of the switched capacitor converter.
