英文摘要	A low power inductorless variable gain amplifier (VGA) for wideband communication systems is presented in this paper. It is a resistor feedback close-loop amplifier based on a proposed wideband operational amplifier. The operational amplifier is constructed by an artificially differential NIP complementary cascode amplifying stage for high gain, and a self-biased N/P complementary source follower for buffer stage to dramatically extend the bandwidth. The proposed VGA is implemented in the standard 0.18 mu m CMOS process, and achieves a 3-dB bandwidth of 470 MHz for 20 dB gain, and also achieves 16 dB NF. It consumes 1.5 mA current from 1.8 V supply voltage (excluding the output buffer for measurement), and the core occupies 0.3 mm(2) silicon area.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000290197700043&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; Nanoscience & Nanotechnology; EI; CPCI-S(ISTP); 0
