摘要：This paper presents the design of CMOS operational transconductance amplifiers (OTAs) with very small transconductance (of order of nano ampere per volt), which uses in very low frequency continuous time filters. This design uses current division technique to reduce the transconductance of OTA. This design is simulated in SPICE tool using 0.25μm technology model file
