In this paper, a wide bandwidth and wide dynamic range AGC amplifler is presented. A push-pull variable gain amplifler (VGA) structure is proposed for wide dynamic rang. Moreover, the bandwidth enhancement technique is used in the post amplifler design to ensure the wide bandwidth and gain of whole circuit. The experimental results demonstrate that the proposed AGC amplifler fabricated in 0.13"m SiGe BiCMOS process, achieves a 23-GHz bandwidth and 36-dB dynamic rang whereas the power and area consumption are 57.6mW and 1.9mm 2 , respectively.
