  3. Abstract:
  4. A new, ultra low-voltage, linear CMOS OTA will be described. A 4th order, 18 MHz low pass Butterworth Gm-C filter has been designed with this new OTA stage for video applications. In this filter a new, fully digital approach has been used for frequency tuning. The THD of the filter for input signal 0.5 VPPis better than -60 dB. All of circuits are designed based on 0.25 um CMOS process technology with a single 1-volt power supply
