A low voltage switched-capacitor circuit that generates an almost constant reference current across process, voltage and temperature (PVT) is proposed. The reference voltage is generated by a low voltage band-gap circuit. The output reference current is obtained by applying the generated reference voltage to a low voltage V – I converter.
General Design Rules 4 Reactors: Reactors are used in steps as detuned filters and are connected in series with capacitors. It must be designed to withstand fundamental and harmonic currents. Capacitors: Capacitors forms the core component in APFC equipment and plays a vital role in power factor correction.

Ceramic capacitors are the most common capacitor type since they are inexpensive, offer a wide range of values, and provide solid performance. Tantalum, OSCO N, and Aluminum Electrolytic capacitors are all polarized (specifically to be used as a bypass capacitor). Tantalum found their niche in low-voltage systems.
