Abstract:
1. A slope compensation circuit for use in a current mode switching regulator, said slope compensation circuit comprising: a first summer circuit for receiving a clock signal and a reference signal as input signals, and for generating a linear signal as an output signal; a multiplier and integrator circuit for multiplying said linear signal with an input voltage signal, and integrating the result for generating a non-linear signal which varies based on a measured value of a current flowing within said current mode switching regulator; a second summer circuit for receiving a first voltage signal corresponding to said non-linear signal and a second voltage signal indicating the difference between an actual voltage level of said current mode switching regulator and the desired voltage level of said current mode switching regulator, and for generating a first output signal which represents the second voltage signal minus the first voltage signal; and a comparator for receiving the first output signal from said second summer as a first input, and said measured value of a current flowing within said current mode switching regulator as a second input, and for generating a second output signal utilized to control current flow within said current mode switching regulator.
