Tunable floating-gate low-voltage transconductor

Presents a six transistor fully differential dual-ended low-voltage (ULV) FGUVMOS operational transconductance amplifier (FGUVMOS-OTA), and a Gm-C filter where the FGUVMOS-OTA is used. The OTA has rail-to-rail operation. A basic Gm-C filter implemented with the OTA is presented. The cut-off frequency of the filter is tunable over almost 6 decades with a supply voltage below 1 V.
