초록
Provided are a variable gain amplifier and a receiver including the same. The variable gain amplifier includes: a gain controller generating a gain control voltage; a variable gain amplifier amplifying an input signal and a feedback signal by using a voltage gain that is linearly proportional to the gain control voltage, and converting the amplified signal into a predetermined magnitude of a signal; and an offset canceller removing an offset from an output signal of the variable gain amplifier and outputting the offset removed result as the feedback signal. The variable gain amplifier includes a plurality of operational transconductance amplifiers.
