SECTION 4 SWITCHED CAPACITOR VOLTAGE CONVERTERS …
www.analog.comSwitched capacitor inverters are low cost and compact and are capable of achieving efficiencies greater than 90%. Obviously, the current output is limited by the size of the capacitors and the current carrying capacity of the switches. Typical IC switched capacitor inverters have maximum output currents of about 150mA maximum.

Introduction to Switched-Capacitor Circuits
www.seas.ucla.eduanalyze switched-capacitor amplifiers, considering unity-gain, noninverting, and multiply-by-two topologies. Finally, we examine a switched-capacitor integrator. 12.1 General Considerations In order to understand the motivation for sampled-data circuits, let us first consider the simple continuous-time amplifier shown in Fig. 12.1(a).
