Abstract
The present invention describes systems and methods for improving the programming of floating-gate transistors. An exemplary embodiment of the present invention provides a floating-gate transistor programming system including an array of floating-gate transistors and a measuring circuit comprising a logarithmic transimpedance amplifier and an analog-to-digital converter. Furthermore, the floating-gate transistor programming system includes an injecting circuit comprising a digital-to-analog converter, wherein the pulsing circuit can inject charge into each of the floating-gate transistors and the measuring circuit can measure a present charge value in one of the plurality of floating-gate transistors.
