Ultra low-voltage floating-gate transconductance amplifier
The minimum supply voltage in low-voltage circuits can be defined as Vsup,min = 2(Vgs+Vsat) [1]. Low-voltage circuits are able to operate on a supply voltage of two stacked gate-source voltages and two saturation voltages. Differential amplifiers are biased with a transistor feeding a differential pair, where the current level is set by the bias transistor. The minimum input voltage in a NMOS i...

This paper presents a 6 transistor fully differential dualended low-voltage (ULV) FGUVMOS operational transconductance amplifier (FGUVMOS-OTA), and a Gm-C filter where the FGUVMOS-OTA is used. The OTA has rail-torail 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 1V.
