A 23-GHZ BANDWIDTH AUTOMATIC GAIN CONTROL AMPLIFIER WITH WIDE DYNAMIC RANGE FOR HIGH SPEED COMMUNICATION

In this paper, a wide bandwidth and wide dynamic range AGC amplifier is presented. A push-pull variable gain amplifier (VGA) structure is proposed for wide dynamic rang. Moreover the bandwidth enhancement technique is used in the post amplifier design to ensure the wide bandwidth and gain of whole circuit. The experimental results demonstrate that the proposed AGC amplifier that is fabricated in 0.13 μm SiGe BiCMOS process, achieves a 23-GHz bandwidth and 36-dB dynamic rang among the recently published AGC amplifiers, whereas the power and area consumption are 57.6 mW and 1.9 mm2, respectively.
