Floating-Gate-MOS Transistor (FGMOSFET) has several applications on analog circuit design; in some cases FGMOSFET simplifies high-complexity circuits because of its inherent properties. On the other side, working with FGMOSFET on subthreshold regime has allowed non-linear function implementation such as exponential and natural logarithm functions. Moreover, working on subthreshold regime is one of...
The aim of this paper is to design analog circuits which develop different computations. This work generalizes the basic idea of the implementation of squaring and square root circuits proposed before to generate nth-power-law circuits and nth-root circuits. The MOSFET's work on the weak inversion region which allows implementing different kinds of non-linear functions. Fundamental circuit operations...
This paper presents the analysis, design and implementation of a Voltage - Current Converter (VIC), for a Memory Current Cell (MIC) in a sample and hold process using Floating Gate MOS transistors and fabricated in 1.2 mum CMOS technology. The mathematical analysis of each cell is focused in show the advantages the floating gate transistor has versus conventional MOS transistor. Also, the cells are...
This paper describes the experimental design of an electronic potentiometer cell (e-pot) to provide reference voltages, using a CMOS floating-gate memory fabricated in 1.2 mum CMOS process. Attention is focus to the fact that the e-pot will be programming applying tunneling and injection hot electrons processes. It takes into account the long-term voltage storage as charge on the floating gate of...
