چکیده
In this study, we designed the OTA circuit for Gm-C active filter using the direct transform method that has capable of various frequency tuning. The OTA make it enable filter design that can be used in various frequency bands due to control trans-conductance by using external voltage control. Our OTA circuit can be used for active filter of CDMA also other device that use other frequency bands. From HSPICE simulation, the external voltage from 0.5V to 1.5V, Trans-conductance varies from 2uS to 222uS. The filter is suitable for any kind of application involving low frequency ranges, and requiring very low power consumption, such as WCDMA products.
