摘要：

Causal relationship between the third-order input intercept point (IIP3) of transconductors and that of doubly-terminated ladder Gm-C filter employing these transconductors is explored and the formula relating both IIP3's is derived. The analytical results reveal that the IIP3 of the ladder Gm-C filter is about 1.2 dBV higher than the IIP3 of the transconductors and the validity of this finding is well confirmed by simulation results.
