An integrated circuit radio transceiver and method therefor includes a
high-pass variable gain amplifier (HPVGA) operably disposed within one of
the transmitter and the receiver front ends operable to provide a linear
variable gain and a substantially constant high-pass frequency corner
that does not vary with changes in gain level settings. The HPVGA
includes an amplifier operably disposed to receive an input signal and to
produce an amplified output based upon the input signal, an adjustable
resistance block operable to adjust resistance based upon a gain control
input and corner drift compensation block operably disposed to provide
corner frequency compensation at the input terminal of the amplifier that
is further coupled to receive the input signal from the adjustable
resistance block.
