Title:
AMPLIFYING UNIT, METHOD OF OUTPUT CONTROL AND CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2008/032782
Kind Code:
A1
Abstract:
[PROBLEMS] To provide, for example, a pulse input type power amplifying unit
that can be operated at low voltage and low power, effectively inhibiting any
generation of harmonic component. [MEANS FOR SOLVING PROBLEMS] The amplifying
unit is provided with at least two amplification circuits, the one and the other
amplification circuits (11,12), composed of multiple amplifiers having output
sides thereof connected to each other, operated at the same frequency. The multiple
amplifiers constructing the one amplification circuit (12) are built up of first
inverting amplifier (M11) inputted with reference pulse (23) and amplifying
the same and inverting amplifier (M12) inputted with inverted pulse (22) resulting
from phase shifting and inversion of the reference pulse (23). The other amplification
circuit (11) is built up of inverting amplifier (M13) and first inverting amplifier
(M14) commonly inputted with other wide pulse (21) with a width greater than that
of the reference pulse (23).
