  • Abstract
    This paper presents a fully differential dual-ended ultralow-voltage (ULV) FGUVMOS operational transconductance amplifier (FGUVMOS-OTA), and a Gm-C filter where the FGUVMOS-OTA is used. The OTA has no internal nodes, rail-to-rail operation and dynamic load. The cut-off frequency of the Gm-C filter is tunable over more than 5 decades. The circuits may be operated with supply voltages down to 200 mV
