摘要：

An improved clock-feedthrough compensation scheme for switched current system is proposed. Both the signal dependent and the constant clock feedthrough terms are canceled by using both nMOS and pMOS current samplers and by adopting a source replication technique. The proposed current memory cell was fabricated with 0.6-mu m CMOS process. Both experimental and theoretical results on clock-feedthrough error reveal substantial reduction over the existing compensation schemes.
