Abstract
A CMOS operational transconductance amplifier and capacitor (OTA=C) integrator which is used for high-frequency operation has been designed and simulated by the SPICE 2G program. The authors have realized the continuous-time OTA=C elliptic low-pass filters by a cascade method and a signal flow graph (SFG) method using only capacitors and OTAs. The frequency characteristics of the OTA=C filters are compared
