Patent ID: 7102433

Claim:
A boosting circuit, comprising: an input circuit part for outputting a differential current proportional to differentiations of input voltages; a bias circuit part for mirroring the differential current, inverting the differential current, and producing an inverted differential current; and an output circuit part for adjusting each magnitude of the differential current and the inverted differential current based on a predetermined ratio size of MOS transistors of the output circuit part, to output an adjusted differential current and an adjusted inverted differential current, adding the adjusted differential current and the adjusted inverted differential current, and producing an output current in a push-pull form; wherein the input circuit part includes: a first differentiation circuit for being inputted with a reference voltage and a first input voltage of the input voltages, and outputting a first differential current; a second differentiation circuit for being inputted with the reference voltage and a second input voltage of the input voltages, and outputting a second differential current; and a current mirror circuit for mirroring the first and second differential currents.
