摘要:
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.
