Voltage differencing gain amplifier (VDGA) and its application [PDF]
2013 13th International Symposium on Communications and Information Technologies (ISCIT), 2013 A circuit realization of the voltage differencing gain amplifier (VDGA) using only tunable transconductance cells is described in this paper. The newly defined element is conceptually a combination of the voltage differencing unit and the current-controlled voltage amplifier.
