Abstract
The optimal choice of output stages in CMOS transconductors in the presence of nonideal effects is analyzed. It is shown that current folding employing source-coupled differential pairs is advantageous versus the conventional approach based on current mirrors. Two versions of a CMOS transconductor, each one using one of the mentioned approaches, have been fabricated in a 0.5μm CMOS technology and tested. Measurement results confirm the linearity improvements of current folding at the output stage.
