Title:
切り替え充電乗算器-除算器
Document Type and Number:
Japanese Patent JP4263216
Kind Code:
B2
Abstract:
The switched charge multiplier-divider according to the present invention is constructed of CMOS devices. Capacitor charge theory is employed to implement the circuit of the switched charge multiplier-divider. The switched charge multiplier-divider includes an output capacitor and controls the voltage across the output capacitor, so that it is proportional to the product of the charge current and the charge-time interval. The switched charge multiplier-divider is ideal for use in the power factor correction (PFC) of switching mode power supplies. Potentially, it can also be applied to automatic gain control (AGC) circuits.
