Abstract
To provide, for example, a pulse input type power amplifying apparatus that can be operated at low voltage and low power, effectively suppressing generation of harmonic component.The amplifying apparatus includes at least two amplification circuits, one and other amplification circuits, composed of multiple amplifiers whose output sides are connected to each other, driven at the same frequency. The multiple amplifiers forming the one amplification circuit are configured with a first inverting amplifier M12 inputting and amplifying a reference pulse, and a second inverting amplifier M11 to which an inverted pulse formed by shifting and inverting the phase of the reference pulse is inputted. The other amplification circuit is configured with the first inverting amplifier M14 and the second inverting amplifier M13 to each of which other wide pulse with a width greater than that of the reference pulse is commonly inputted.
