In order to avoid disappearance of output symbols in accompaniment with DC
voltage fluctuations occurring at the timing of switching gain in
receiving systems for mobile telephones or the like compatible with
W-CDMA systems, the present invention provides a variable gain amplifier
circuit, a gain control circuit and a mobile communication terminal
apparatus, in which a PGA section is comprised of PGAs having different
amplification widths continuously arranged in plural stages as in, two
coarse adjustment PGAs, a fine adjustment PGA and a coarse adjustment PGA
from the input side to the output side; and a gain control circuit has a
memory storing a history of gain control with regard to the PGA section
and a logic circuit individually controlling gain of each PGA.
