چکیده
The supply and threshold voltage scaling has been proposed for low-voltage/low-power design [1, 2, 3]. The programmable floating-gate circuits [3, 4] can be used to implement low-voltage/low-power digital circuits. The threshold voltages are shifted using reversed supply voltages and UV-light. The supply voltage may be reduced and the current level is determined by the threshold shift. Before this class of circuits is used, a tuning or programming of the floating gates is done with short-wave UV-light [3, 5]. The chip is exposed to UV-light and the supply rails are used to provide the specific floating-gate offsets (threshold shift) in an adaptive reversed bias mode. Two important conditions are established during the programming:

Multi-input Quasi-floating Gate Mosfets with Analog Inverter Used in Circuits
The multiple-input floating gate transistors were used to simplify the design of multiple valued logic. The Quasi-floating gate node have a well defined DC operating point. The multi-input quasi-floating gate is used for low voltage applications because its effective threshold voltage will be controllered to a low value.

In this paper we present a 2 input analog Current-Starved Pseudo-Floating Gate (CSPFG) inverter with capacitive feedback. The analog CSPFG inverter suppresses low frequencies due to the active, local feedback. This inverter can be used in designing filters where a narrow band pass or reject is the main goal. Typical applications are detection of high frequency components in sensor signals, i.e....

متن کاملA Proposition on Floating Gate Neuron MOS Macromodeling for Device Fabrications
A neuron MOS transistor has a floating gate and multiple input gates which are capacitively coupling with the floating gate. Dramatic reduction in the number of transistors and interconnections was achieved by employing the neuron MOS in circuit designs. Since the neuron MOS gate electrode is electrically floating, it is not necessarily easy to calculate the floating gate potential using circui...
