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 multipli er.
