In this thesis, we propose a low voltage low power wide-tuning 4th-order butterworth low-pass OTA-C channel selection filter. It is implemented by using TSMC 0.35£gm 2P4M CMOS technology. The drain voltage of triode-biased input transistors of the OTA is regulated through an active-cascode loop for low power and wide-tuning range. The Gm-C channel selection filter can be programmed from 0.5 to 12MHz. The OTA also employs a circuit to reduce the OTA output current in a high transconductance mode and the total power consumption of filter is suppressed below 3mW.
