This invention relates to a voltage comparator with an input for an analog signal and an output for a digital signal, comprising an inverter which has an input coupled to the comparator input and an output coupled to the comparator output, and comprising at least two MOS transistors coupled to each other, at least one of the two MOS transistors being of the floating gate type.

Voltage comparator with floating gate MOS transistor

The present invention relates to a digital-to-analog converter having a plurality of inputs for digital signals and an output for an analog signal. It comprises a current amplification circuit having an input and an output coupled to the converter output, and a plurality of floating gate MOS transistors corresponding to the plurality of converter inputs and having their source terminals coupled together and to a first reference of potential. The converter has drain terminals coupled together and to the input of the amplification circuit, and has control terminals coupleable, under control from the inputs of the plurality, to different references of potential having selected fixed values.
