The proposed filter is based on a new \u00b1 0.75 V second-generation current conveyor with digitally programmable current gain. The input stage of the current conveyor is realized using two complementary MOS differential pairs to ensure rail-to-rail operation. The output stage consists of a Class-AB CMOS push-pull network, which guarantees high current driving capability with a 47.2 \u03bcA standby current. The digital programmability of the current conveyor, based on transistor arrays and MOS switches, provides variable current gain using a digital code-word. Two approaches for implementing current conveyors with programmable current gain either greater or less than one are described. The fully programmable universal filter and the proposed digitally programmable current conveyor circuits are simulated using PSPICE with 0.25 \u03bcm CMOS technology from MOSIS. <\/jats:p>","DOI":"10.1142\/s0218126609005411","type":"journal-article","created":{"date-parts":[[2009,7,3]],"date-time":"2009-07-03T10:01:54Z","timestamp":1246615314000},"page":"875-897","source":"Crossref","is-referenced-by-count":35,"title":["FULLY PROGRAMMABLE UNIVERSAL FILTER WITH INDEPENDENT GAIN-\u03c9<sub>0<\/sub>-Q CONTROL BASED ON NEW DIGITALLY PROGRAMMABLE CMOS CCII"],"prefix":"10.1142","volume":"18","author":[{"given":"TAREK M.","family":"HASSAN","sequence":"first","affiliation":[{"name":"Electrical Engineering and Electronics Department, German University in Cairo (GUC), New Cairo City-Main Entrance Al Tagamoa Al Khames, Cairo, 11835, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SOLIMAN A.","family":"MAHMOUD","sequence":"additional","affiliation":[{"name":"Electrical Engineering and Electronics Department, German University in Cairo (GUC), New Cairo City-Main Entrance Al Tagamoa Al Khames, Cairo, 11835, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1142\/S021812660500257X"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2005.852922"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1007\/s10470-006-9703-3"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1109\/TCT.1970.1083067"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1109\/19.85337"},{"key":"rf6","volume":"138","author":"Liu S.
