摘要：
We discuss a systematic, semi-analytical approach to design of large signal current mode amplifiers. The main steps of the recently developed linearization technique, Individual Suppression of Complex Harmonics, are presented along with a short overview of existing linearization techniques. The technique is illustrated by two flavors of-design of a transconductor amplifier, implemented in SiGe. The measured performance is featured by large signal linearity of 78 dBc, linearization efficiency of 20 dBc and high robustness to process variations (the scatter of 90% of results is within +/- I dB). Although the procedure is demonstrated on particular examples, it is applicable to wide class of current mode amplifiers.
