Abstract

With a slight modification in current differencing buffered amplifier (CDBA), a new block, namely differential-input current feedback amplifier (DFCA), is obtained. It is shown that, with two additional MOSFETs, this modified CDBA structure can be utilized as a linearly tunable transconductor, which can also be converted to a variable-gain amplifier or an analogue multiplier.
