This paper presents a broadband inductor-less variable gain amplifier (VGA) with a linear-in-dB gain control characteristic and DC-offset cancellation.The proposed VGA is composed of a variable gain block,an exponential voltage generator,a DC-offset canceller with common-mode voltage correction,and a gain peaking block.To achieve the broad band and reduce the chip area,the gain peaking block employs an inductor-less gain peaking scheme to compensate the high frequency gain drop of the variable gain block and the DC-offset canceller.The VGA fabricated in 0.13μm SiGe BiCMOS technology achieves a 3-dB bandwidth of 7.5 GHz and a variable gain range from -10 to 30 dB.Due to the inductor-less design,the die area is only 0.53 × 0.27 mm2 which is the smallest among other similar reported works.At 10-Gb/s,the VGA consumes 50 mW power from a single 1.2 V supply and exhibits an output data jitter of less than 30 pspp.
